Title:
特異値分解(SVD)を使用する統合型時空間最適フィルタ(JSTOF)
Document Type and Number:
Japanese Patent JP2009505529
Kind Code:
A
Abstract:
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.
