A wired/wireless communication receiver includes an equalizer through multipath delay estimation and a signal receiving method. The receiver includes a delay spread estimation unit, a factor updating unit, and an equalizer. The delay spread estimation unit estimates a delay spread value of a received signal and uses a symbol boundary information signal to determine a filtering tap length value and a filtering step size value from an estimated delay spread value. The factor updating unit updates filtering factors using the filtering tap length value and the filtering step size value. The equalizer compensates distortion of the received signal using the filtering factors.

Wired/wireless communication receiver and method for improving performance of equalizer through multipath delay spread estimation

Provided is a method of compensating for energy loss and eliminating inter-symbol interference (ISI) and inter-chip interference (ISI) in wireless signals, and a rake receiver for wireless LANs adopting the same. The rake receiver compensates for energy loss of a CCK signal transmitted in a multi-path wireless channel environment and eliminates ISI and ICI from the received CCK signal because a DFE structure per chip used for calculating ICI components, is connected in parallel with a DFE structure per symbol, thus eliminating ISI and ICI components.
