Abstract :
Turbo equalization (TEQ) is an iterative technique which lowers the transmission error rates allowing the equalizer and the decoder to exchange information. The objective of this work is to answer the question if turbo equalization may offer significant improvement and at what cost, in the EDGE systems. The simplified SISO MAP equalizer and decoder are used and various schemes of frame and block data processing are analyzed. Conclusions are drawn from simulations based on definition of the TCH/F43.2 EDGE channel.
