摘要
多频带OFDM(正交频分复用)已作为支持高速、低功率和点对点无线通信UWB的重要解决方案。通过介绍多频带OFDM系统的原理,对多频带OFDM的UWB系统进行仿真研究。通过仿真得出多频带OFDM-UWB系统工作稳定,接收信号准确,并且能在短时间内减小功耗。
Multiband orthogonal frequency divison multiplexing（MB - OFDM） has been considered as a prominent solution for ultra wideband （UWB） technology supporting high speed, low - power and point - to - point wireless communications. This paper introduced the principle of the MB - OFDM system, studied the MB - OFDM - UWB system. The simulation result showed that this system works very steadily, and receives the signals correctly , meanwhile it costs little time to minish the system＇s power loss.
