Abstract

Abstract:

Solving the problem of algorithm in modern communication channel, a new method of quasiNewton least mean square adaptive equalization is proposed. By replacing inverse matrix calculation of LMS/Newton correlation function by symmetric positive-definite Hesse matrix, the proposed algorithm reduces the influence of traditional autocorrelation matrix estimate error for the algorithm convergence. Equalization simulation shows that higher convergence speed and lower bit error rate are obtained.

Key words: least mean square algorithm, new quasi-Newton algorithm, adaptive equalization, bit error rate
