ABSTRACT:
Aspects of a method and system for rate>1 SFBC and/or STBC using hybrid maximum likelihood (ML)/minimum mean squared error (MMSE) estimation are presented. Aspects of an exemplary system may enable rate 5/4 coding in diversity communication systems that utilize SFBC and/or STBC. A transmitting station may utilize SFBC or STBC to generate and/or concurrently transmit a plurality of signals symbols, which are encoded to enable rate 5/4 transmission. A receiving station may decode rate 5/4 encoded signals utilizing a hybrid decoding method. The hybrid decoding method may result from application of a plurality of decoding methods when decoding the rate 5/4 encoded signals. In an exemplary aspect of the invention, the hybrid method may utilize ML/MMSE estimation in combination with zero forcing (ZF) interference cancellation. The combination may be referred to as hybrid ML/MMSE estimation.
