Abstract
The present method resides in a user destination receiver to exploit the structure of the transmitted signals to design filters that yield improved performance. Moreover, the computational cost of designing these filters can be reduced and the demodulation complexity can be kept low. Further, the present method enables determining the order of decoding the transmitter sources. The present method provides group MMSE decision feedback decoding for the case when all the sources transmit at fixed pre-determined rates and the MCS employed by each source is known to the destination. The present method includes a filtering technique and an order and filter computation process, both improvements over previous efforts at group MMSE decision feedback decoding.
