Abstract

We design a self-iterating soft equalizer (SISE) consisting of several suboptimal equalizers that are weak individually but, when working together, show good performance. In order to process correlated soft information through serially concatenated modules, a sophisticated method to generate the extrinsic information is proposed that suppresses the correlation effect between the soft information of suboptimal equalizers. This algorithm performs well in turbo equalization system as well as the classic uncoded equalization system. The performance advantages are validated with bit-error-rate (BER) simulations and extrinsic information transfer (EXIT) chart analysis.
