Low power UWB RF transceiver for wireless headset

Abstract

In this paper, the UWB RF transceiver architecture based on a direct chaotic communication system is introduced for wireless headset applications. The direct chaotic communication technology can realize excellent low data rate UWB communication. The low power RF transceiver with chaotic UWB signal of 3 GHz /spl sim/ 5 GHz is implemented for MP3 audio transmission. This simply configured system prototype performs non-coherent detection without up/down mixers. The system is expected E/sub b//N/sub 0/ of 18 dB for PER /spl les/ 10/sup -2/ at 32 bytes length of PSDU, and power consumption of 20 mW in case of 0.13 micron CMOS RFIC fabrication.
