Patent ID: 7817740

Claim:
A method for processing received information in a wireless communication system, the method comprising: sorting a received RF signal in a multiple input multiple output (MIMO) system into a plurality of layers based on an SNR; generating at least one estimated symbol based on one of said plurality of layers, wherein said at least one estimated symbol is a minimum mean square error with linear equalization (MMSE-LE) estimate; generating at least one cancellation signal resulting from canceling interference from said received RF signal based on each of said at least one estimated symbol; generating at least one subsequent estimated symbol based on a subsequent one of said plurality of layers; generating at least one subsequent cancellation signal resulting from canceling subsequent interference from each of said at least one cancellation signal based on each of said at least one subsequent estimated symbol; deriving soft information based on said at least one estimated symbol, and said at least one subsequent estimated symbol; and decoding said received RF signal based on said derived soft information.
