摘要：UWB (Ultra Wideband) technology is having high data rate due to the large number of pulses that can be created in short time duration. In this paper different modulation techniques are used for UWB signal. In any receiver the LNA is the first step after antenna, so it is very crucial component. This paper contemplates the performance comparison of different modulation technique in UWB receiver with the wide band LNA. The wide band LNA is implemented using Agilent’s ADS software. With ADS wideband LNA gain achieved is 12 dB and is incorporated in SIMULINK model of UWB receiver. This work evaluates the BER performance of modulation techniques with AWGN and SV channel. The performance of UWB receiver with BPSK modulation technique in AWGN channel is better than PPV and PPM. However PPV modulation technique improves performance with SV channel than BPSK and PPM modulation technique
