摘要

摘要

En 中文
This paper extends a recently proposed approach to pipeline an adaptive filter to the case of least mean square (LMS)-based adaptive decision feedback equalizer. It is shown that by certain manipulation of the equalizer weight update equation, a pipelined architecture can be realized which generates the output at the first stage itself and thus is free from any latency. The proposed method overcomes certain limitations of the conventional approaches in that due to the absence of any latency, there is no compulsion to employ delayed LMS algorithm for coefficient adaptation and thus no compromise with convergence rate becomes necessary.
