Power allocation optimization for uplink MC-CDMA systems

Abstract

In this paper, we consider the joint transmitter and receiver for uplink MC-CDMA systems. The equation of the MMSE joint transmitter-receiver is expressed. We apply an optimization technique by rewriting the equation of the joint transmitter and receiver for uplink MC-CDMA systems as second-order cone programming (SOCP) which can efficiently be solved numerically by the existing polynomial convergence software packages. Numerical examples show that the joint transmitter-receiver optimization yields the lower BER compared with the MMSE receiver for both perfect channel estimation and imperfect channel estimation case
