Patent ID: 8345733

Claim:
A communications device, comprising: a transceiver operating in a wideband code division multiple access/high speed downlink packet access communication system; a memory storing computer instructions; and a controller coupled to the memory and the transceiver, wherein the controller, responsive to executing the computer instructions, performs operations comprising: converting a carrier signal to a baseband signal; calculating a time domain channel estimation from the baseband signal; applying a Fast Fourier Transform to the time domain channel estimation to produce a frequency domain channel estimation; performing a frequency domain tap weight calculation according to the frequency domain channel estimation without performing a matrix inversion to perform the frequency domain tap weight calculation; applying an inverse Fast Fourier Transform to the frequency domain tap weight calculation to produce a time domain tap weight calculation; equalizing the baseband signal according to the time domain tap weight calculation using a linear filter to provide an equalized signal; processing the equalized signal to convey audio signals from an audio system of the communications device and to convey visual signals from a display of the communications device; and performing an equalizer function according to one group among a group of equalizer techniques comprising a least mean square equalization, and a recursive least square equalization.
