ABSTRACT

In this paper, we proposed a PO-THMA(pulse order-time hopping multiple access) scheme in UWB(ultra-wide band) system. The proposed PO-THMA UWB system using two-dimensional code combines MHP(modified Hermite polynomial) pulse order and time hopping code. The MHP pulses have a mutually orthogonal property between different order and that property makes simultaneous transmission at the same time slot regardless of collision in the THMA UWB system. We derive the general form of correlation function for MHP pulses and multiple access interference and analyze BER of the scheme over AWGN(additive white Gaussian noise) channel. Theoretical analysis and simulation results show that proposed PO-THMA UWB system increases transmission capacity or has better BER(bit error rate) than conventional THMA UWB system. The proposed PO-THMA UWB system is expected to be utilized in the high data rate wireless communication system with low power and low complexity. With these benefits, the studied PO-THMA UWB system can be used in low power sensor networks and short range wireless communication applications with high transmission rate.
