Abstract:
1. A method for using a joint decoding engine in a wireless device, comprising: determining a first symbol stream and a second symbol stream in a received multiple input multiple output (MIMO) signal, a scaled channel estimate for a wireless transmission channel, and a scaled noise covariance of the MIMO signal; whitening the scaled channel estimate and the first symbol stream; performing max log maximum a posteriori (MLM) processing on the whitened first symbol stream to produce a first data stream; de-rate matching and turbo decoding the first data stream to produce a decoded first data stream, wherein de-rate matching comprises replacing bits in the first data stream before turbo decoding; performing hard successive interference cancellation (SIC) or soft SIC on the second symbol stream if SIC is enabled; and whitening, performing max log maximum a posteriori (MLM) processing, de-rate matching, and turbo decoding the second symbol stream to produce a decoded second data stream.
