Abstract
This invention provide parallel interference cancellation for wireless communication base stations. Received user inputs symbols are spread by means of pseudo-noise sequences to form user input chip vectors. These are added together and interpreted to form chip vectors of interference samples. These chip vectores are despread to form interference output symbols by pseudo-noise sequences. The interference output signals are subtracted from the received user input symbols to obtain a first estimate of transmitted symbols. This process may be continued for two or more iterations to obtain better interference cancellation.
