Patent ID: 6850190

Claim:
A wireless fading-channel demodulator comprising: a receiving-processing portion which receives and converts sub-array group analog communication signals that are received via M antenna sub-array groups, into digital input signals, multiplies the digital input signals by corresponding weighted vector elements, and sums the products for each sub-array group to generate M diversity-beamforming signals; a signal magnitude and phase processing portion which multiplies the magnitude and phase of a representative digital input signal for each of the M sub-array groups by the corresponding one of the M diversity-beamforming signals and outputs the M products; a final beam output portion which sums the M products output from the signal magnitude and phase processing portion and outputs a final output signal; and a weighted vector calculation portion, wherein the weighted vector calculation portion: calculates, from the digital input signals, a weighted vector that comprises the weighted vector elements; selects the representative digital input signal for each sub-array group from among the digital input signals; and calculates and outputs the magnitude and phase of the selected representative digital input signal for each sub-array group.
