Abstract

In this paper, we describe a technique to incorporate side information into the channel estimation operation at the receiver in a GSM-based system. The technique has a complexity comparable to that of the standard method. Simulations indicate that in terms of coded bit error rate (BER), our technique produces gains of about 0.8 dB in a static channel, and 1 dB in non-dispersive Rayleigh and Rician fading channels. Similar gains are achieved for uncoded BER and probability of detected error. Such gains are desirable in a cellular system. They are considerable in a satellite system, where link margin is at a high premium
