A UWB Pulse Shapes Modulation Scheme Based on Modified Hermite Polynomials

摘要

Considering Ultra wide band (UWB) system which transmits data information using ultra-short pulses, a pulse shape modulation UWB system based on orthogonal UWB pulse is proposed, which is on the basis of the orthogonality and non-direct component of modified Hermite polynomial function. The simulation result shows that the method can not only improve the performance, but also decrease the bit error rate.
