Abstract:
1. A method, comprising: processing, at a communication device, a plurality of received signals to decode information corresponding to a first information stream transmitted via i) at least one first spatial stream, and ii) a multiple input multiple output (MIMO) communication channel; generating, at the communication device, a plurality of modified received signals corresponding to the first information stream using i) the decoded information and ii) the plurality of received signals; generating, at the communication device, bit metric values for a second information stream in the plurality of received signals using i) MIMO maximum likelihood (ML) demodulation, ii) the plurality of modified received signals, and iii) channel and modulation information for interfering signals, wherein the second information stream is transmitted via at least one second spatial stream and wherein the at least one second spatial stream was modulated separately from the at least one first spatial stream; and decoding, at the communication device, information corresponding to the second information stream using the generated bit metric values.
