Abstract	In this letter, an ultra-wideband (UWB) direct chaotic communication technology is proposed. Based on this system, a 2-GHz wide chaotic signal is directly generated into the lower band of the UWB spectrum, i.e., 3.1-5.1 GHz. The information component is modulated by the chaotic signal based on the chaotic-on-off keying modulation scheme which results in a series of chaotic radio pulses. At the receiver, a simple noncoherent envelope detector is used as an energy collector. Various system design parameters and tradeoffs are discussed in the letter in order to meet the low-complexity, low-power consumption, and low-cost requirements while still compliant with the Federal Communications Commission UWB regulation. The average power consumptions for various operating data rates and the technical feasibilities of implementing the above system as low-cost integrated circuit are also addressed. Additionally, the system performance in both additive white Gaussian noise (AWGN) channel and various types of multipath channels are provided in order to further demonstrate the capability of the proposed system.
