Systems and methods for performing iterative interference cancellation

摘要

Systems and methods are provided for performing iterative interference cancellation. The systems and methods include receiving a plurality of codewords and processing the plurality of codewords using a channel decoder to obtain a decoder output. The systems and methods further include determining, based on the decoder output, whether a stopping criterion is satisfied, and cancelling interference from the plurality of codewords based on the decoder output in response to determining that the stopping criterion is not satisfied.

1. A method for performing iterative interference cancellation in an outer, interference cancellation, loop that includes an iterative channel decoder that processes a plurality of codewords in an inner, decoding, loop, the method comprising:
receiving, using control circuitry, the plurality of codewords; processing the plurality of codewords using the iterative channel decoder to obtain a decoder output, wherein the processing of the iterative channel decoder is performed until the processed plurality of codewords satisfies an inner-loop stopping criterion; determining whether the decoder output satisfies an outer-loop stopping criterion; and in response to determining that the outer-loop stopping criterion is not satisfied, cancelling interference from the plurality of codewords based on the decoder output.
