| Abstract: | This paper begins with the introduction of the principle of basic structure of Turbo codes in CDMA2000, as well as basic encoding and decoding means. And then, we provide a plan to realize the function of encoding and decoding on FPGA. Finally,through simulation,we find the plan decreases the complexity and time-delay of decoding at the price of little performance loss,and the results turn to be rather good. Thus,this plan is tested to have a lot of practical value. |
