Optimum Time Shift Autocorrelation for Time Hopping UWB System using PPM Technique

This paper presents the optimum time shift of pulse position modulation (PPM) to achieve minimum autocorrelation and consequently minimum bit error rate, in time hopping UWB communication system. The minimum autocorrelation is calculated for the famous pulses used in UWB, the Gaussian pulses, from zero order to fifth order. The obtained result is achieved by MATLAB simulation for practical TH-UWB system.
