Abstract
A new CMA adaptive beamforming algorithm based on modified conjugate gradient method is proposed. This algorithm focuses on a new technique for data block modification method with conjugate gradient, and overcomes the shortcoming of traditional CMA algorithms, which has slow convergence speed or vast complexity. Computer simulations show that the algorithm has better convergence performance and better SINR capability than other kinds of CMA algorithms.
