摘要：

A flexible chaotic ultra-wideband (UWB) communication system with an adjustable channel spectrum is proposed. Since the chaotic UWB bandwidth (BW) is independent of the data rate, the system band plan can be flexibly organized for various communication environments. The proposed system can overcome the spectral inefficiency and RF power wastage that is typically observed in conventional methods by utilizing adjustable channel allocations. A novel chaotic signal generator is designed with an adjustable frequency range of 3.54.5 GHz and BW of 70-620 MHz. The chaotic UWB transceiver system is implemented in CMOS 0.18-mu m technology, and it features tunable chaotic signal generation and adaptive detection. The system performance is evaluated for digital data transmission rates of up to 15 Mb/s.
