Patent ID: 8472877

Claim:
An interference cancellation (IC) method in a communication system, comprising: receiving multi-paths of a signal; and performing iterative interference cancellation to remove multi-path interference; wherein performing iterative interference cancellation to remove multi-path interference comprises: estimating a Signal-to-Interference-plus-Noise Ratio (SINR) at each of a plurality of pre-determined rake receiver finger delays; and performing successive Channel Estimation (CE) and interference cancellation on rake receiver fingers in a sequential order from strongest to weakest according to estimated SINRs for the rake receiver fingers; wherein successive channel estimation and interference cancellation comprises evaluating rake receiver fingers in the sequential order of strongest to weakest SINRs for the rake receiver fingers and the channel estimation of a next weakest rake receiver finger does not start until interference of a previous weakest rake receiver finger is removed from a sample buffer.
