摘要:
卫星通信系统波形体制的定义,是体制标准制定的基础工作之一。既要考虑到体制波形自身的特点,也要考虑到系统中器件特性对信号传播的影响。对OFDM体制波形、DFT-s-OFDM体制波形在经过载荷放大器后的射频特性进行测量;通过EVM、PAPR、信噪比解调门限、效率等指标,评估两种体制信号在单载波、四载波场景下的性能质量,进而对波形体制的选择给出建议。

摘要:
Power domain non-orthogonal multiple access combined with a universal filtered multi-carrier(NOMA-UFMC)has the potential to cope with fifth generation(5G)unprecedented challenges.NOMA employs powerdomainmultiplexing to support several users,whereasUFMC is robust to timing and frequency misalignments.Unfortunately,NOMA-UFMC waveform has a high peak-to-average power(PAPR)issue that creates a negative affect due to multicarrier modulations,rendering it is inefficient for the impending 5G mobile and wireless networks.Therefore,this article seeks to presents a discrete Hartley transform(DHT)pre-coding-based NOMA enabled universal filter multicarrier(UFMC)(DHT-NOMA-UFMC)waveform design for lowering the high PAPR.Additionally,DHT precoding also takes frequency advantage variations in the multipath wireless channel to get significant bit error rate(BER)gain.In the recommended arrangement,the throughput of the systemis improved by multiplexing the users in the power domain and permitting the users with good and bad channel conditions to concurrently access the apportioned resources.The simulation outcomes divulge that the projected algorithm accomplished a gain of 5.8 dB as related to the conventional framework.Hence,it is established that the proposed DHT-NOMA-UFMC outperforms the existing NOMA-UFMC waveform.The key benefit of the proposed method over the other waveforms proposed for 5G is content gain due to the power domain multiplexing at the transmitting side.Thus,a huge count of mobile devices could be supported under specific restrictions.DHTNOMA-UFMC can be regarded as the most effective applications for 5G Mobile andWireless Networks.However,the main drawback of the proposed method is that the Fourier peak and phase signal is not easily estimated.

摘要:
In this paper, the impact of atmospheric turbulence is investigated and analyzed for the Free Space Optical Mobile Ad Hoc Networks (FSO MANET) using the Network Simulator NS-3. The FSO channel random intensity fluctuations have been modeled using the Exponentiated Weibull (EW) distribution. Further, the FSO module has been implemented and integrated with NS3 using the FSO propagation model and the FSO error models. The computation of the key performance indicators (KPI) mainly the throughput and the packet delivery ratio (PDR) shows that the network density affects the network performance. Its effect was illustrated for the different turbulence regimes, strong and weak. It is found that the throughput and PDR values decrease as the number of mobile nodes becomes larger. For instance, at 150 kbps and in the presence of strong turbulence with 25, 50, and 75 nodes, the PDRs are 77%, 76%, and 73% respectively. Moreover, the throughput and PDR values in the strong turbulence regime are lower than those in the weak turbulence regime for the same date rate. The throughput in the strong turbulence regime with 75 mobile nodes at the data rate 150 kbps is 2100 kbps while it is 2300 kbps in the weak turbulence mode at the same rate.

摘要:
A jamming signal such as single and multiple Continuous-Wave (CW and MCW) interferences have been shown to have severe effects on the quality of the received signal in wireless communication. This paper presents an approach of a low-complexity algorithm that compares the performances of using Adaptive Notch Filter (ANF) direct and lattice forms structures based on second-order Infinite Impulse Response (IIR) Notch Filter (NF) for the detection and mitigation of CW and MCW interferences in QPSK communication systems. The approach method consists of two ANFs, adaptive IIR NF and adaptive IIR NF . The present algorithm can estimate and mitigate each CWI and computer their power in Time-Domain (TD). In results for performance comparison, the lattice IIR NF structure outperforms the direct IIR NF structure for detection and removal jamming and has a better Bit Error Ratio (BER). Furthermore, compared with the case of full suppression (), both cases (direct and lattice form) work better for low and high-power jammers. Also, compared to the case without an IIR NF, the presented algorithm can detect and mitigate, track hopping frequency interference, and improve BER performance.

摘要:
土库曼语是粘着性语言,形态变化丰富及复杂,其中动词是最复杂的一个语法范畴。土库曼语动词“-ber”的形式及语义比较复杂,含有较多的语义功能,不仅可以作实义动词,也可以作体助动词。作体助动词时,除了作持续体,还可以作利他体、进行体、起始体等,此外还可以与时结合。本文根据土库曼语口语资料及书面语实际情况做基础语料,运用“意义–形式–语义”方法,探讨“-ber”的不同形式、不同结构及特点,以及否定形式及其意义。总之,试图透析“-ber”的多维语义功能。

摘要:
N-continuous orthogonal frequency division multiplexing(NC-OFDM)is a promising multicarrier transmission waveform conceived for improving sidelobe suppression performance.To reduce the severe inband interference in traditional NC-OFDM,we have proposed low-interference signal modeling for NC-OFDM.However,spectral leakage and error may be undesirably increased owing to the limited continuous differentiability of the smooth signal.In this paper,the low-interference scheme is investigated in terms of power spectrum density(PSD)and error performance,under the parameters of the highest derivative order(HDO)and the length of the smooth signal,to prove and quantify its advantages over traditional NC-OFDM.In the context of PSD,sidelobe decay is evaluated upon considering two discontinuous points due to the finite continuity of the smooth signal and its higher-order derivatives.Furthermore,it was shown that the low-interference scheme incurs small signal-to-noise ratio(SNR)loss and bit error rate(BER)for a short length of the smooth signal or a small HDO compared to traditional NC-OFDM.Meanwhile,due to the cyclostationarity loss imposed by the smooth signal,an effective solution is suggested for the time synchronization in a practical system.Based on analyses and simulation results,the trade offs between sidelobe suppression and BER are studied.

摘要:
The article introduces Non-Orthogonal Multiple Access(NOMA)and Filter Bank Multicarrier(FBMC),known as hybrid waveform(NOMAFBMC),as two of the most deserving contenders for fifth-generation(5G)network.High spectrum access and clampdown of spectrum outflow are unique characteristics of hybrid NOMA-FBMC.We compare the spectral efficiency of Orthogonal Frequency Division Multiplexing(OFDM),FBMC,NOMA,and NOMA-FBMC.It is seen that the hybrid waveform outperforms the existing waveforms.Peak to Average Power Ratio(PAPR)is regarded as a significant issue in multicarrier waveforms.The combination of Selective Mapping-Partial Transmit Sequence(SLM-PTS)is an effective way to minimize large peak power inclination.The SLM,PTS,and SLM-PTS procedures are applied to the NOMA-FBMC waveform.This hybrid structure is applied to the existing waveforms.Further,the correlated factors like Bit Error Rate(BER)and Computational Overhead(CO)are studied and computed for these waveforms.The outcome of the work reveals that the NOMA-FBMC waveform coupled with the SLM-PTS algorithm offers superior performance as compared to the prevailing systems.

摘要:
针对现有的联合预编码算法忽略多用户之间的直传链路而导致通信性能下降的问题,本文以最小和均方误差为设计准则,提出了一种发射端的所有用户集中优化的联合预编码算法.首先,由于MSMSE优化问题的非凸性,将单流信号输入的多用户等效为一个多流信号输入的基站进行优化处理,其中基站的预编码矩阵由所有发射端的用户的子预编码矩阵构成,原非凸的MSMSE优化问题被转化为发射端用户的子预编码矩阵和中继收发矩阵2个子优化问题分别进行处理.其次,根据最小均方误差接收滤波理论,直接求解出接收滤波矩阵的优化表达式.发射端用户的子预编码矩阵的子优化问题通过求解条件获得,中继收发矩阵的子优化问题被转化成一个标准的半正定问题进行优化处理.最后,发射端用户的子预编码矩阵、中继收发矩阵和接收滤波矩阵联合迭代至收敛,得到优化后的预编码矩阵.实验仿真结果表明:提出的联合预编码算法在系统和均方误差性能和误码率性能上都有明显的提升,并且仿真进一步验证了算法有快速的收敛速度.

本论文考察了电极生物膜反应器(BER)中溶解氧(DO)的浓度梯度,及生物膜电极系统的电化学行为和反硝化性能.实验结果表明,电化学反应和微生物的呼吸共同影响着BER中DO的消耗.为了研究DO对BER反硝化性能的影响,本论文自行设计了一套水电解反应器(WER),通过调节WER的电流强度可以改变进水DO浓度.结果证明,BER的反硝化速率常数和硝酸盐氮的去性能会随着DO的增大而降低.通过透射电镜观察了WER的外加电流强度为0和150mA时,生物膜上的微生物,发现DO的增大会引起菌种的变化.
