Patent ID: 7233777

Claim:
A method for processing AM signals, comprising: receiving RF data in an overloaded signal environment, said received RF data comprising cochannel AM signals received in the same frequency range and at the same time; and separating each of said cochannel AM signals from other cochannel AM signals of said received RF data; wherein said separating comprises estimating each of said cochannel AM signals based on said received RF data; and wherein said separating further comprises: providing an initial estimate for each of said cochannel AM signals; providing a first improved estimate for each of said cochannel AM signals based at least in part on said initial estimates for each of said cochannel AM signals and said received RF data; and providing a second improved estimate for each of said cochannel AM signals based at least in part on said first improved estimates for each of said cochannel AM signals and said received RF data.
