Performance analysis of a New Time-Varying LMS(NTVLMS) adaptive filtering algorithm

A New Time Varying LMS (NTVLMS) algorithm is proposed and its performance is analysed. The proposed algorithm is applied to adaptive noise cancellation system. The investigations have indicated better performance of the proposed NTVLMS algorithm as compared to LMS, NLMS, RVSSLMS, NVSSLMS and TVLMS algorithm for stationary signal in terms convergence rate and output SNR except MVSSLMS algorithm. For Speech signals proposed NTVLMS algorithm is better compared to other algorithms in White Gaussian noise Environment and NLMS algorithm performs well in Conference noise, Engine noise & Traffic noise environments in terms of output SNR.
