WIRELESS COMMUNICATIONS DEVICE INCLUDING A JOINT DEMODULATION FILTER FOR CO-CHANNEL INTERFERENCE REDUCTION AND RELATED METHODS

摘要

The wireless communications apparatus can include a wireless transmitter and a wireless receiver carried by the housing, and the housing. The wireless receiver may comprise a joint demodulation filter for reducing co-channel interference between the co-channel interfering signal and the desired signal, joint demodulation filter is between the Viterbi (Viterbi) decoder, the input and the Viterbi (Viterbi) decoder of claim It may include a first signal path comprising a first filter. Joint demodulation filter input and the Viterbi (Viterbi) decoders between a and co-channel interfering signal on to the channel impulse response estimation value generation to for a linear finite impulse response (FIR; linear finite impulse response) modeler (modeler) to contain a second It may include a further signal path. In addition, the third signal path may include the input and the Viterbi (Viterbi) decoder may be between, whitened matched filter for generating a channel impulse response estimate for the desired signal (whitened matched filter).
