摘要： In a collaborative, multiple input, multiple output wireless communication system, a transmitting device transmits a peak-limited pilot signal to a receiving device. The receiving device independently synthesizes the same pilot signal transmitted by the transmitting device. The synthesis process involves precoding the pilot signal and peak limiting the precoded pilot signal. The receiving device receives a signal r that represents the product of (i) a channel matrix H between the transmitting device and the receiving device and (ii) the peak-limited pilot signal yp(n)′ plus noise η, i.e. r=Hyp(n)′+η. The synthesized, peak-limited pilot signal can then be used by a channel estimator to determine an estimated channel matrix Ĥ. Thus, the estimated channel matrix Ĥ represents a closer estimate of the channel matrix H than conventional channel estimation processes and, thus, can provide better corresponding performance than conventional MIMO wireless communication systems.

摘要： A method of acquiring, at a receiver, fine timing synchronization for an Orthogonal Frequency Division Multiplexing (OFDM) signal as transported over a channel, includes determining an impulse response of the channel; dynamically creating a window function corresponding to the impulse response; and selecting a multiplicity of samples of the OFDM signal in accordance with the window function, where the multiplicity of samples are time aligned with an OFDM demodulator. A corresponding synchronizer includes a correlator for cross correlating a received preamble with a known preamble to provide an impulse response corresponding to the channel; a window generator configured to dynamically create a window function corresponding to the impulse response; and a selector configured to select a multiplicity of samples of the OFDM signal in accordance with the window function, where the multiplicity of samples are time aligned with a Fast Fourier Transform window associated with an OFDM demodulator.
