Abstract :
In this paper, performance comparison of frequency-domain (FD) minimum mean square error (MMSE) turbo equalization for OFDM and single-carrier (SC) transmission in ST-BICM systems is investigated. In particular, we propose a joint formulation of the frequency- domain OFDM and SC MMSE turbo equalizer which enable to bring out similarities and differences between the two transmission schemes. This provides a new view on the topic. The relevance of the proposed approach is confirmed by comparing the lower bound of the iterative equalizing process with the corresponding analytical results. Simulation results over multipath Rayleigh block fading channels for various MIMO configurations show the benefits provided by each scheme.
