Investigation And Realzation Of CCK Demodulation Based On 802.11b

This subject is to design and implement the CCK based on 802.11b after analyzing the modular function, parameters required and learning the latest development abroad and domestically.Similar to other kind of communication systems, the demodulation modular of CCK includes two parts such as RF receiver and processor of IF and baseband. The paper introduces the 802.11b at first.Then analyzes the basic theory and arithmetic of CCK. Describe the process of CCK demodulating algorithm with Matlab. Presents the design of RF receiver which is used to CCK demodulate. Expound the theories and the experiments of the filter, mixer and VCO. At last, design the blueprint of the IF and baseband processor which is based on RF2948 and RF3000.
