Abstract :
The chaotic UWB communication system based on IEEE 802.15.4a is proposed for wireless headset applications. A compact architecture can be implemented by using a chaotic UWB signal and a non-coherent detection scheme. The chaotic UWB generator is designed with the BW of 3.1 to 5.1 GHz, and a baseband process is realized on an FPGA including an adaptive decision and a channel code for non-source coded data stream. The system performance is evaluated by transmitting MP3 audio/voice and measuring PERs at 32 byte length of a PSDU for the system sensitivity and the interferer compatibility. The proposed system can be an excellent candidate for short-range connectivity services, as well as an inexpensive system with good capability for narrow-band interferences
