Abstract: A novel ultra-widcbandCUW13) transceiver based on codcshifted reference(CSR) was introduced. By modeling and simulation on MATLAI3, the bit error performance sensor network environment It shows that the CSR receiver of the system was analyzed and compared under wireless is more rohust to narrowhand interference than the conventional transmitted reference( I}R) receiver and with a lower complexity. Moreover, simulation the shorter results reveal the relation between the shifting used, the better N13I codes and the NI3I mitigation capacity of CSR-UWI3 receiver or the more random mitigation capacity will be achieve, which provides guidelines for optimization shifting codes code and improving performance for CSR transceiver.
