ITERATIVE MULTIPATH INTERFACE CONCELLATION SYSTEM AND METHOD

摘要

A system and method for Interference Cancellation (IC) . One aspect relates to iterative interference cancellation with iterative finger delay adaptation. The interference cancellation method comprises receiving multi-paths of a signal; and performing iterative interference cancellation to remove multi-path interference, wherein the performing iterative IC comprises estimating a Signal-to-Interference-plus-Noise Ratio (SINR) at each of a plurality rake receiver fingers having pre-determined delays, and performing successive Channel Estimation (CE) and IC on rake receiver fingers according to their estimated SINRs, and wherein the CE of a next finger does not start until interference of a previous finger is removed from a sample buffer. The method further comprises improving estimated rake receiver finger delays by using an early-date structure at each finger.
