dc.description.abstractIn this paper, we consider a cooperative network, where base station (BS) and relay station (RS) are enabled with a large number of antenna. For such network, the achievable rate and power efficiency is investigated. In uplink scenario, received signals across the RS and BS are detected with zero forcing (ZF) detector. We have also chosen ZF technique for precoder design, which is utilized across the RS in end-to-end signal transmission.When statistics of channel matrix and precoding matrix areknown then SNR and achievable rate can be eaisly found by using random matrix theory. In such network, performance is also measured under different cooperation protocol. We have derived the tractable lower bound for the achievable rate which has also been numerically verified. Numerical results analyze the impact of a large number of RS and BS antenna for determining the achievable rate, where total transmit power remains constant. On the other side, the impact of a total number of RS and BS antenna on power efficiency has also been investigated where variation with total power to RS antennas is observed keeping BS antenna constant and vice versaen_US
