| Abstract: | This paper firstly analyzes the amplitude and phase errors in quadrature demodulation receiving system,and points out the disadvantage of the equalized method that had putted forward.Then,a full new style of real time adaptive equalized method,on the basis of the characteristics of UWB,is presented.Meanwhile,the serial algorithm is modified according to the characteristics of UWB,and a high speedy pipelined algorithm,which fits realization of FPGA,is also introduced.Finally,the two algorithms are compared with each other by simulations. |
