摘要

A method for performing wireless communications and an associated apparatus are provided, where the method is applied to an electronic device. The method includes the steps of: receiving at least one data stream, wherein each data stream from the at least one data stream is transmitted from a wireless channel; in a first iteration, utilizing a Maximum Likelihood (ML) estimator to perform demapping processing on at least one portion of the at least one data stream to obtain Log-Likelihood Ratios (LLRs) of the first iteration and performing Turbo decoding according to the LLRs of the first iteration to generate resultant LLRs of the first Iteration; and in at least one following iteration, utilizing a Max A Posterior (MAP) estimator to perform demapping processing on at least one portion of the at least one data stream and performing Turbo decoding, successively, in order to cancel interference due to the wireless channel.
