Abstract:
1. A wireless communication apparatus for generating beamforming weights, comprising: a hop generator for generating a frequency-hopping sequence for a group of frequency subcarriers that constitute less than all of a frequency band; a time domain response buffer in a memory for providing a time domain response information corresponding to at least one frequency subcarrier in the group of frequency subcarriers; a discrete Fourier transform processor for performing a discrete Fourier transform on the time domain response information corresponding to the at least one frequency subcarrier; a component of a beamforming weight module for generating the beamforming weights based on the discrete Fourier transform on the time domain response information and according to a predetermined algorithm; and a scheduler for providing a location of the group of frequency subcarriers to the discrete Fourier transform processor.
