A Study on Iterative Channel Decoding Techniques Applied to GSM Full-Rate Channels

Authors: F. Jordan, K.-D. Kammeyer
Abstract: In this paper, we discuss applying iterative, decoding algorithms (turbo-equalizer) to GSM speech channels. Although the turbo-equalizer under realistic time-variant channel scenarios has a high potential, we only get a minor performance gain when compared to soft-decision algorithms. Certain constraints of the GSM coding scheme prevent better results. In this paper, we discuss the transition from a very simple data transmission model to a full GSM-compatible system and compare the resulting bit-error-rates (BER).
