Abstract
Official abstract text for this publication.
An interference canceller comprises a composite interference vector (CIV) generator configured to produce a CIV by combining soft and/or hard estimates of interference, an interference-cancelling operator configured for generating a soft projection operator, and a soft-projection canceller configured for performing a soft projection of the received baseband signal to output an interference-cancelled signal. Weights used in the soft-projection operator are selected to maximize a post-processing SINR.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for cancelling interference from a received baseband signal in a CDMA system, comprising: generating at least one composite interference vector (CIV) by combining estimates from interfering subchannels, generating a soft-cancellation operator, and performing a soft cancellation of the received baseband signal to output an interference-cancelled signal.
