Comparative study of turbo equalisers using convolutional codes and block-based turbo codes for GMSK modulation

Abstract

In contrast to previously proposed turbo equalisers, where typically non-iterative channel decoders were used, this paper compares the performance of partial-response GMSK turbo equalisers using two different encoders, namely block BCH turbo codes and convolutional codes. The BER performance is assessed over non-dispersive Gaussian channels, and dispersive Rayleigh fading channels.
