Channel Equalization b ased Convex Optimization

Arra y radar interchannel mismatch may seriously degrade the performance of the array signal processing unless some form of compensation is employed. The compensation can be achieved by means of equalizer. Coefficients of equalizer can be solved by the least-squares theory. This paper introduces convex optimization to enhance the performance of equalizer. Simulation results show that convex optimization is very effective and reliable. Keywords—channel mismatch; least-squares; convex optimization.
