An adaptive method called the block iterative equalizer (BIE) method, for compensating time-varying channel effects, is presented. The BIE method offers convergence and tracking capabilities comparable to the popular RLS (recursive least squares) methods. Furthermore, the BIE algorithm performs with O(N) computational complexity, typically O(10N). The stability of the algorithm is achieved by performing an iterative pseudoinverse of the equalizer data matrix. The performance of the BIE algorithm is more robust than that of the LMS (least mean square), NLMS (normalized LMS), or RLS algorithms when the condition number of the Grammian matrix is high. This property translates into minimal noise enhancement and stable operation.
