Method and apparatus for detecting a desired signal in the presence of an interfering signal

摘要

In accordance with an embodiment, there is provided a method comprising receiving, at a receiver, a desired signal and an interfering signal, wherein the interfering signal was transmitted with a modulation unknown to the receiver; identifying a likely modulation corresponding to the modulation with which the interfering signal was transmitted; and decoding the desired signal using a modulation dependent multiple-input multiple output (MIMO) detection, wherein the modulation dependent MIMO detection is based at least in part on the identified likely modulation corresponding to the modulation with which the interfering signal was transmitted, wherein the modulation dependent MIMO detection includes maximum likelihood (ML) detection.

1. A method, comprising:
receiving, at a receiver, a plurality of signals, wherein the plurality of signals comprises (i) a desired signal and (ii) an interfering signal, and wherein the interfering signal is transmitted with a modulation that is unknown to the receiver; accessing, by the receiver, a plurality of modulations, wherein one of the plurality of modulations is likely used for transmitting the interfering signal; for each modulation of the plurality of modulations, generating a corresponding estimate of the interfering signal, wherein a plurality of estimates of the interfering signal is generated corresponding to the plurality of modulations; based on the plurality of estimates of the interfering signal, generating a first estimate of the interfering signal; and based on the first estimate of the interfering signal, estimating the desired signal.
