| Abstract: | WLL is a wireless access system that uses a wireless link to connect subscribers to their local exchange in place of conventio nal copper cable.This paper describ es a digital receiver for the pro-posed wideband CDMA WLL system.The s ystem constitute and network structure of WLL are described ,then reverse link channel structure and design specification of the reverse link receiver are described,and the functions of code acquisition an d code tracking module are discussed.The reverse link receiver can oper-ate at clock frequency up to 65.536MHz. |
