UWB (Ultra Wide Band) technology is a reliable transmission scheme for wireless communication with high data rates. It is called as impulse radio, impulse radar or carrier free ultra high resolution .UWB occupies a bandwidth of more than 25% of a center frequency, or more than 1.5GHz . It is a carrier free (base band) technique, which will greatly reduce the complexity and cost of transceiver. UWB can be characterized with ultra short duration pulses called monopulse which has excellent immunity in interference from sensitivity or multipath effects or fading problem. In this paper we examine different types of pulse shaping, modulation techniques and different types of demodulation are simulated and evaluated the BER(bit error rate) in the presence of the AWGN (additive white Gaussian noise ) . In this paper BER are Compared to examine the best modulation technique with monopulse.

This study is focused on the basis of UWB such as pulse shaping and the modulation schemes. To fulfill the objective of the study two different types of pulse shaping and three different types of modulation schemes for UWB system are considered for performance evaluation. By considering of pulses and three different types of modulation techniques the BER (bit error rate) performance of the modulation techniques will be evaluated in the presence of the AWGN .Simulation techniques are used and comparisons are made for Gaussian first and Second Derivative pulse modulation schemes using BER performance evaluation in the presence of AWGN channel for UWB. The results show the BER performance of BPSK modulation scheme to be the best in AWGN channel as compared to the other two modulation techniques considering Gaussian first derivative pulse and the the BER performance of OOK modulation scheme to be the best in AWGN channel as compared to the other two modulation techniques considering Gaussian second derivative pulse.
