Sub-Terahertz Low Power UWB Communication Link for WPAN

Abstract

proposed is  ultra-wideband (UWB) wireless communication system for transmitting digital information in the terahertz frequency range on the basis of analog  noise carrier with a low level of radiation. The digital information at the transmitter is inserted using code spectrum modulation of noise signal. The bit error rate (BER) performance is analyzed for different signal to noise ratios at the receiver at different bit rates. The proposed UWB wireless communication system is characterized by high noise immunity and the ability to secure transmission of information "in the noise" for the received information signal below the noise level. The designed UWB sub-terahertz communication link at 70 microwatt transmit power is suitable for wireless personal area networks.

Keywords: ultra-wide band UWB, WPAN, code spectrum modulation.
