Abstract :
Our work focuses on semi-blind equalization techniques when applied to GMSK-based mobile communication systems. Starting from the works developed in (F. Alberge et al, SPAWC´99), a new semi-blind block algorithm is proposed to provide reliable communication through a typical mobile multi-path channel. The algorithm is shown to have performance similar to that of the Viterbi algorithm in a fixed setting, while being more efficient in time-varying situations.
