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 the 5^(th) generation mobile communication(5G)system,better bitrate,better power consumption,and better Bit Error Rate are needed.To meet all these requirements in 5G,the waveform is important.Although the Orthogonal Frequency Division Multiplexing(OFDM)modulation scheme has been commonly used in 4G,it is difficult to meet the requirements of 5G.A lot of candidate waveforms are discussed in the 5G system included Filter Bank Multicarrier(FBMC),Universal Filtered Multicarrier(UFMC),Filtered OFDM(F-OFDM),and Generalized Frequency Division Multiplexing(GFDM),etc.However,since GFDM is no longer widely used,in this paper,FBMC,UFMC,and F-OFDM modulation schemes are discussed and compared with OFDM.Power Spectral Density(PSD),Bit Error Rate(BER),Transmitted Signal Power,Peak Average Power Ratio(PAPR)and Bit Rate parameters of the modulation schemes are studied and compared with OFDM.FBMC demonstrates to be the most promising modulation scheme for 5G systems.

摘要:
Multi and single carrier waveforms are utilized in cellular systems for high-speed data transmission.In The Fifth Generation(5G)system,several waveform techniques based on multi carrier waveforms are proposed.However,the Peak to Average Power Ratio(PAPR)is seen as one of the significant concerns in advanced waveforms as it degrades the efficiency of the framework.The proposed article documents the study,progress,and implementation of PAPR reduction algorithms for the 5G radio framework.We compare the PAPR algorithm performance for advanced and conventional waveforms.The simulation results reveal that the advanced Partial Transmission Sequence(PTS)and Selective Mapping(SLM)methods enhanced the throughput and gain of the 5G waveforms.Furthermore,we have also analyzed the performance of Orthogonal Time Frequency Space Modulation(OTFSM)based on a single carrier system and found that PAPR is significantly low and is best suited to fading environments.It is seen that the conventional algorithms lower the PAPR but increase the complexity.The proposed PTS and SLM have shown good performance with low computational complexity.

摘要:
MIMO-OFDM系统因其高速数据传输优势成为无线移动通信的关键技术,但是其高峰均功率比(PAPR)一直是技术瓶颈.为了降低系统的PAPR和计算复杂度,本文基于传统SLM算法,提出一种无边带信息的STBC MIMO-OFDM系统降低峰均比混沌加扰算法.该算法采用了混沌序列,发射端不需要发射边带信息,同时信号进行分块扰码也降低了系统计算复杂度.理论分析和仿真表明,本文算法可以获得良好的峰均比性能.

摘要:
Non-orthogonal multiple access(NOMA)is gaining considerable attention due to its features,such as low out-of-band radiation,signal detection capability,high spectrum gain,fast data rate,and massive D2D connectivity.It may be considered for 5G networks.However,the high peak-to-average power ratio(PAPR)is viewed as a significant disadvantage of a NOMA waveform,and it weakens the quality of signals and the throughput of the scheme.In this article,we introduce a modified NOMA system by employing a block of wavelet transform,an alternative to FFT(Fast Fourier transform).The modified system combines the details of fractional frequency and time analysis of NOMA signals.In this correspondence,we utilize an advanced partial transmission scheme(PTS),and selective mapping(SLM),and present a genetic algorithm(GA)for SLM to investigate the peak power performance of a WT-based NOMA system.The performance of WT-SLM,WT-PTS,and WT-SLM-GA methods is compared with that of the traditional NOMAbased SLM and PTS methods.The simulation results demonstrate that the proposed system effectively reduces PAPR in comparison with the traditional schemes.

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.
