Abstract:
1. A method performed in a receive node of a communication network to perform interference cancellation (IC), the method comprising: using IC receiver, performing a first stage processing a symbol of interest contained in a first composite signal, the first composite signal being a signal in a chip domain; and using the IC receiver, performing a second stage processing the same symbol of interest contained in a second composite signal, the second composite signal also being a signal in the chip domain, wherein the first stage processing comprises: wherein the second stage processing comprises: wherein the second composite signal is based on the interference-reduced version of the first composite signal, and wherein in the step of second stage generating the second stage symbol estimates, the previous stage symbol estimates are the first stage symbol estimates or the second stage symbol estimates generated in a previous run of the second stage processing.
