Construction of projection operators for interference cancellation

摘要: Interference cancellation is performed in a CDMA receiver by projecting received signal onto subspace that orthogonal to selected for removal. An interference matrix or combined vector used construct an interference-canceling projection operator. Confidence weights may be provided components of the based on estimation errors relative strengths interfering signals. Complexity reduction operator achieved providing simplifying approximations remove terms and operations. A linear transformation applied rows and/or columns prior construction projection. techniques configured processing signals transmit-diversity system receive-diversity using time frequency-domain implementations space wave-number transceiver.
