Abstract

Fundamentals of fuzzy logic, fuzzy logic system, equalizer, adaptive equalizer and fuzzy adaptive equalizer are described in this chapter. A new fuzzy adaptive equalizer with extended Kalman filter adaptation (EKFAE) had been derived in this chapter for communication channel equalization. The merits of EKFAE as compared with three other types of short listed adaptive equalizers, namely: decision feedback recursive least-squares adaptive equalizer, recursive least squares (RLS) based FAE and least mean squares (LMS) based FAE are faster convergent speed and lower steady state BER.
