MIMO V-BLAST Detection Performances on Single RF Using Convolutional Code with Rate of 1/3

摘要

MIMO technology is needed in the world of wireless communication (wireless) which acts as a pair of antennas on the transmitter and receiver sides that work on multipath components. The MIMO system design is able to maximize data rates to support data flow and improve overall system reliability. So, it is concluded that this technology has access to data communication that is reliable, fast, and efficient in bandwidth usage. However, the disadvantage of MIMO is that any use of an antenna on the receiver side requires a RF front-end that is as large as the number of antennas. So, for a large size antenna, it is not effective. Therefore, RF front-end on the receiver side requires a single RF technique with the number of antennas as needed that aims to minimize the number of RF front-end. In this research, a simulation is carried out to analyze the performance of the single RF technique at the receiver side of the MIMO system using V-BLAST detection technique. V-BLAST is a channel coding technique that is used to minimize errors during large and fast data transmission processes. So, this technique aims to reduce the quantity of the Bit Error Rate (BER). The antenna to be used has a 2x2 dimension based on a single RF. The modulation that will be used is 64- QAM by using a 1/3 rate convolution encoder code. The results obtained by this research are improving performance and minimizing RF front-end by using the V-BLAST technique in the MIMO system where the observed parameters are the comparison of Bit Error Rate (BER) to Signal to Noise Ratio (SNR) which will be shown in the BER towards SNR curve.
