Based on the method of parallel > tangents, the block-LMS algorithm is modified, and the block momentum-LMS algorithm is proposed. The new algorithm has lower computational complexity than the LMS algorithm. It converges significantly faster than the block-LMS algorithm when the input signal is coloured. The time-constant, mean and meansquare convergence conditions and the misadjustment of the proposed algorithm are derived. As a special case, an accurate meansquare convergence condition is obtained for the block-LMS algorithm. Extension to the frequency domain is also discussed. Comprehensive experimental results on system identification and .channel equalisation are presented that validate the theoretical findings. © lEE, 1997.
