Wireless ultra-wide band in wireless personal area network

Abstract

This project focuses on the performance efficiency of the UWB in WPAN technology. A lot of advantages concerning this technology related on bandwidth efficiency, high data rate, power consumption, high spectrum, more robustness rather than the other technology such as Wi-FiAnd WiMax. A lot of modulation technique is performed on WPAN as a modified technique to enhance the performance of the Bit Error rate and channel capacity. Focusing of the physical layer of the WPAN, The modification will hit the modulation (QPSK, BPSK, 16-QAM,32-QAM,64-QAM) and the convolution code (1/2,2/3,3/4,). The study on theData rate of (110 Mbps, 200 Mbps, and 480 Mbps) for the four types of channel (CM1 or SV1,CM2 or SV2, CM3 or SV3, CM4 or SV4).Various modulation techniques are used, and each one of them will be called on its appropriate code rate on Matlab (3/4,5/8,11/55 (which is QPSK)). Besides, three essential systems are used to enhance the BER Vs SNR which is (MB-OFDM, DS-UWB, DS-CDMA or DS-SS). So this project will show us the importance of this technology and how its moreEfficient and robust.
