| Abstract: | This paper first points out the errors affecting the performance of ultra wide band quadrature demodulation receiver. Then a method for real time correcting the amplitude and phase errors of UWB quadrature demodulation receiver using 2PFIR filters is presented, according to the high speed, large data quantity of UWB. An algorithm designing the complex coefficients 2PFIR filters is also offered, followed by a practical example. |
