摘要： A communication system based upon frequency-domain MIMO processing is disclosed. A transmitting device (20) of the communication system transforms time-domain signals (S1-3 [M]) into frequency-domain signals (S1-3 [K]) , and weights (22) each frequency-domain signal to form weighted frequency-domain signals (X1-3 [K]) with each weighted frequency-domain signal (X1-3 [K]) being a function of each frequency-domain signal. The transmitting device (20) transmits weighted time-domain waveforms as a function of the weighted frequency-domain signals (X1-3 [K]) . In response thereto, a receiving device of the communication system provides frequency-domain samples that are a function of the one or more weighted time-domain waveforms and weights each frequency-domain sample to form one or more weighted frequency-domain samples with each weighted frequency-domain sample being a function of each frequency-domain sample. The receiving device decodes the weighted frequency-domain sample to obtain the information represented by the time-domain signals.

摘要： Pilot sequences are constructed from distinct "classes" of chirp sequences that have an optimal cross correlation property. Utilization of chirp sequences for pilot sequences results in pilot sequences that have optimal or nearly-optimal cross correlation and auto-correlation properties.

摘要： A method for reducing interference within a communication system is provided herein. The method comprises the steps of receiving a signal y(n), where y(n) comprises a desired signal, s(n), and a co-channel interfering signal, i(n), wherein s(n) and i(n) are not time-synchronized, converting y(n) into a frequency-domain signal Y(k) (105), calculating a weight vector W(k) (109), wherein W(k) is based on s(n) and i(n), and additionally based on a time offset T existing between s(n) and i(n), and applying W(k) to Y(k) (111) in order to equalize the desired signal, s(n), and reduce co-channel interference i(n).
