METHOD AND APPARATUS FOR EQUALIZING SIGNALS

摘要

A system and apparatus are disclosed for a method and apparatus for equalizing signals. An apparatus that incorporates teachings of the present disclosure may include, for example, an equalizer having a channel estimation calculator for calculating a time domain channel estimation from a baseband signal, a Fast Fourier Transform processor for translating the time domain channel estimation to a frequency domain channel estimation, a tap weight calculator for calculating a frequency domain tap weight according to the frequency domain channel estimation, an inverse Fast Fourier Transform processor for translating the frequency domain tap weight calculation to a time domain tap weight calculation, and a filter for equalizing the baseband signal according to the time domain tap weight calculation.

1. A communications device, comprising:
a transceiver operating in a wideband code division multiple access high speed downlink packet access communication system; a memory that stores 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;translating 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;translating the frequency domain channel estimation to a time domain tap weight calculation;equalizing the baseband signal according to the time domain tap weight calculation to provide an equalized signal; andrestoring signal integrity to the baseband signal based on the equalized signal as a restored baseband signal.
