Abstract :
IEEE802.16e standard proposes a full-rate space-time block code (STBC) achieving the optimum compromise between diversity and multiplexing gains (scheme C). When applied on modulated and FEC encoded data, under the constraint of practical feasibility, we prove the necessity for an iterative turbo-like receiver to outperform the spatial multiplexing structure (scheme B). Exploiting the particular definition of the code, we derive a reduced-complexity minimum mean square error (MMSE) turbo-equalizer and simulations show its efficiency.
