Wireless communication system with interference filtering and method of operation thereof

A method of operation of a wireless communication system comprising:

• 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 including activating a first interference aware log-likelihood ratio module and a second interference aware log-likelihood ratio module;
• activating a second symbol detector for generating an interference log-likelihood ratio from the interference input signal including activating a third interference aware log-likelihood ratio module and the fourth interference aware log-likelihood ratio module;
• and
• jointly decoding a decoded bit by iteratively refining the interference log-likelihood ratio through the first interference aware log-likelihood ratio module and the third interference aware log-likelihood ratio module for negating the interference input signal and iteratively refining the desired log-likelihood ratio through the second interference aware log-likelihood ratio module and the fourth interference aware log-likelihood ratio module for enhancing the desired input signal.

A wireless communication system comprising:

• a first symbol detector for receiving a desired input signal;

• a third interference aware log-likelihood ratio module, in the second symbol detector, for generating an interference log-likelihood ratio from the interference input signal;
• and
• a desired channel decoder coupled to the second interference aware log-likelihood ratio module for 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.
