摘要： An interference cancelling matched filter (ICMF) may include an antenna array for receiving a signal burst including a training sequence therein, and an adaptive space-time filter connected to the virtual antenna array and having settable filter coefficients. The ICMF may further include a channel impulse response estimator for estimating a channel impulse response based upon the training sequence, and a signal blocker operatively connected between the channel impulse response estimator and the adaptive space-time filter so that the filter coefficients thereof are set based upon the training sequence and not the whole signal burst.

摘要： A receiver for a mobile communication system includes a channel equalizer for receiving a burst and generating a soft decision output associated with the burst, a soft decision correction circuit follows the channel equalizer and a decoder receives and decodes a block of bursts. The soft decision correction circuit calculates a correction factor based on the soft decision output for the burst and applies the correction factor to the burst prior to the burst entering the decoder.

摘要： A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation.

摘要： 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 Cholesky and eigenvalue decompositions. 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
