Abstract :
Chirp UWB has the feature of low power consumption, high processing gain and low cost. However, the multiple-access schemes for chirp UWB are limited. They face many difficulties when considering the implementation, bandwidth efficiency and multipath channel. The novel scheme proposed in this paper offers a new multiple-access solution for chirp UWB. It takes advantages of some unique characters of chirp UWB signals and spread spectrum technology. It works well in the multipath channel. Small multiple-access interference (MAI) is achieved as well as bandwidth efficiency. The authors present the details of our proposed scheme and the simulation results in a 4-user situation.
