Co-channel interference disturbs the spectral efficiency in cellular radio systems. A co-channel interference reduction method using a constant modulus algorithm (CMA) adaptive array antenna is proposed. When we apply an adaptive array antenna to reduce co-channel interference, a co-channel interference signal may be captured. In this method, the replica of the interference signal is generated and then eliminated from the received signal, and thus the desired signal can be obtained. Computer simulation results of GMSK modulation confirm that a CMA adaptive array antenna that uses this method can reduce co-channel interference more than a conventional CMA adaptive array antenna
