Abstract
In certain embodiments, an equalization device for a wireless communication receiver includes multiple adjusting means coupled between corresponding multiple weighting means and a combining means. The multiple weighting means performs a weight process on a received multipath signal to obtain multiple weight results, respectively, according to a plurality of adjustable weight coefficients. The multipath signal includes a known training sequence and user data that may both experience channel fading. The adjusting means compares the weight results of the known training sequence with respective multiple known reference signals, and respectively adjusts the weight coefficient of each weighting means by utilizing the comparison results so that the weighting means weight the user data by utilizing the adjusted weight coefficient. The combining means combines the weight results of the user data to obtain a combined equalization signal. Certain embodiments of the equalization device may be implemented on a mobile terminal to mitigate the effects of wireless channel fading.
