A Cochannel Interference Cancellation Algorithm based on Twice Iterations

In order to increase system capacity on the limited frequency resources of the mobile communications networks,the method that reduce reuse factor is usually adopted,and however this would result in cochannel interference to communications networks.This paper proposes a cochannel interference cancellation algorithm based on twice iterations.The proposed algorithm,based on the improved MIC algorithm,could solve the problem that the estimated parameter values by MIC algorithm often lag behind the real value under the condition of time-varying parameters.The simulation results indicate that the algorithm could effectively cancel the cochannel interference and maintain stable performance.
