Abstract

A method of operation of a wireless communication system includes: receiving a desired input signal and an interference input signal; activating a first symbol detector for generating a desired log-likelihood ratio from the desired input signal; activating a second symbol detector for generating an interference log-likelihood ratio from the interference input signal; and jointly decoding a decoded bit by iteratively refining the interference log-likelihood ratio for negating the interference input signal and iteratively refining the desired log-likelihood ratio for enhancing the desired input signal.

Description

Technical field [0001] The present invention generally relates to a wireless communication system, and more particularly, to a system for managing interference in a wireless communication system. Background technique [0002] The next-generation cellular system is in the process of deployment, in which the cell size becomes smaller, so that inter-cell interference becomes an urgent problem in terms of packet error performance. In addition, because both pico cell and femto cell services have been recently activated, interference signals from these local cells have also become a major source of degrading the performance of desired signals. In the case of point-to-point communication in which a single transmitter sends a signal to a designated receiver, there is an agreement between the serving node (eNodeB) and the user equipment (UE) so that they can share the system parameters required to decode the desired signal, such as Modulation and coding scheme (MCS), signal exchange sign...
