1 Efficient Realization of an ADFE with a New Adaptive Algorithm

Authors: Abhijit Mitra, C. Ardil, N. Praveen Kumar

Abstract:

Decision feedback equalizers are commonly employed to reduce the error caused by intersymbol interference. Here, an adaptive decision feedback equalizer is presented with a new adaptation algorithm. The algorithm follows a block-based approach of normalized least mean square (NLMS) algorithm with set-membership filtering and achieves a significantly less computational complexity over its conventional NLMS counterpart with set-membership filtering. It is shown in the results that the proposed algorithm yields similar type of bit error rate performance over a reasonable signal to noise ratio in comparison with the latter one.

Keywords: adaptive algorithm, Decision feedback equalizer, Block based computation, Set membership filtering
