Performance Analysis of TAS/MRC Systems over η-μ Fading Channels with Equal Correlation

This paper analyses the outage probability and average bit error rate (ABER) of a multiuser Transmit Antenna Selection/Maximal-ratio combining (TAS/MRC) system over equally correlated η-μ fading channels. In TAS/MRC system the best antenna, based on channel state information (CSI) is used for information transmission and MRC is performed in the receiver. The expressions of PDF for SNR of the system, outage probability and ABER have been derived considering equally correlated model of η-μ fading channels. Study of correlation effect and the number of diversity branches on the performance of the communication model have been carried out for different fading parameters and reported in the numerical result and discussion section. This can be a guideline to the design engineers to optimize their performance of communication model. The results are also validated with the computer simulation and found to be correct. Key-Words: ABER, Equal correlation, η-μ fading, Outage probability, Multiple-Input-Multiple Output (MIMO), TAS/MRC.
