The transpose-form LMS(TLMS)algorithm is ideal for high-speed,parallel realization of FIR adaptive filter,this algorithm has recently been exploited in the design of equalizer for high bit-rate QAM digital radio modems [1].This paper analyzed the condition for the step size to guarantee the convergence of the mean squared error(MSE)of the TLMS algorithm.Gompared with the existing convergence bound for TLMS algoritha,the condition derived in this paper is more useful in practical application.Computer simulation results are given to verify the conclusions obtained in this paper.
