Full diversity linear precoding with low complexity turbo equalization
Résumé
A new linear equalization is proposed for OFDM- CDM (OFDM code division multiplexing) with iterative decod- ing. Using recent results in turbo-equalization, we derive the equalization coefficients for an optimized precoding decoder. The proposed method keeps a low complexity even with large size precoders and high order modulations. Theoretical and simulation results show that full diversity is achieved after three or four iterations.
