Design Low Power Detection QPSK-Transceiver for UWB Techniques

Abstract

Abstract This paper presents the implementation and investigation of the quarter phase shift keying low power detection. The receiver is designed and modeled using Matlab. It was tested for different values of SNR with a constant input signal power of 100 mW. The FFT based receiver performance is measured theoretically by transmitting 1000 information symbols from the transmitter end with 7 dB improvement at Bit Error Rate BER of 10e−4, Multi Modulation Techniques Recommended and not Recommended are simulated in this research. In this research the modulation method was selected on the basis of reducing rates of the interference in the UWB communication techniques and the essential modulation should have several types of spectrum random distribution methods to reduce the level of the interference on account of the impulse train that transmitted.
