JOINT SPACE-TIME OPTIMUM FILTERS (JSTOF) USING SINGULAR VALUE DECOMPOSITIONS (SVD)
摘要
<p>A filter for reducing co-channel interference within a communications receiver may include a multi-channel, space-time filter circuit that filters n signal parts that have been split from a communications signal by jointly estimating space-time filter weights and multi-channel impulse responses (CIRs) based upon a singular value decomposition (SVD). The filter may further include a multi-channel, matched filter circuit that receives multi-channel signals from the multi-channel, space-time filter circuit and has a filter response that is provided by a channel impulse response estimation from the space-time filter circuit.</p>
