dc.description.abstractIn this paper, we have considered a relay assisted cooperative network, where relay station (RS) and base station (BS) have very large but finite number of antenna. The data detection is done by linear zero forcing (ZF) technique assuming BS and RS have imperfect channel state information (CSI). We derive a new analytical expression for the uplink rate in different channel imperfection scenario. In single hop signal transmission from mobile users (MU) to BS via RS, large number of RS and BS antennas play a vital role over the fixed channel error variance. For dealing with large MIMO, we have used the property of random matrix theory (specially Wishart Matrix decomposition). We have drawn the relation, where uplink rate in single hop signal transmission is the function of number of RS and BS antenna, both link channel error variance and other parameter also. Keeping other parameters constant the uplink rate vs number of RS and BS antenna has been numerically validated for large MIMO perspective under suitable simulation parameter.en_US
