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： The present invention relates to surfacing material which may emit radiation in response to exposure to a given light source. Such surfacing material may be polymeric based, and e.g., fiber based, and may be used in relatively low-light areas, including low-light areas as applied to vehicular applications. The fiber-based or molded materials may emit radiation in response to exposure to a selected light source and may be used in relatively dimly lit areas. The materials may also provide a visible contrast to other objects located adjacent their surface which do not emit radiation. Optical brighteners and luminous particles may be included in the materials to make them luminous.

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). 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.

摘要： Apparatus, and an associated method, for the receive part of a receiving station, such as a mobile station or other transceiver of a cellular communication system. Selection is made of filter characteristics to be exhibited by an adaptive, input noise whitening filter. A noise estimator estimates a noise component of a noise sequence. An autocorrelation estimator estimates the noise-component autocorrelation. A determination is made as to whether the autocorrelation exceeds a threshold. If so, filter characteristics are selected to cause the input noise whitening filter to operate to inject whitening noise into the received sequence.

摘要： A wireless communications device may include a housing and a wireless transmitter and a wireless receiver carried by the housing. The wireless receiver may include a joint demodulation filter for reducing co-channel interference between a desired signal and a co-channel interfering signal which may include an input receiving samples of the desired signal and the co-channel interfering signal, a Viterbi decoder, and a first signal path between the input and the Viterbi decoder comprising a first filter. The joint demodulation filter may further include a second signal path between the input and the Viterbi decoder and comprising a linear finite impulse response (FIR) modeler for generating a channel impulse response estimate for the co-channel interfering signal. Additionally, a third signal path may be between the input and the Viterbi decoder and include a whitened matched filter for generating a channel impulse response estimate for the desired signal.

摘要： A wireless communications receiver includes a memory configured to store offset values corresponding to respective gain settings. A gain controller is configured to continuously select one of the gain settings based on amplitude of a received signal. An amplifier is configured to amplify the signal based on the selected gain setting. An offset estimator is configured to determine an updated offset value as a function of both a time-average value of the signal and a previously-stored offset value. The previously stored offset value is an offset value that was stored in the memory at a time prior to the gain controller switching to the currently-selected gain setting from a previously-selected gain setting.
