%0 Journal Article %T ANALYSIS OF DATA RATE TRADE OFF OF UWB COMMUNICATION SYSTEMS %A Rajesh Thakare %A Kishore Kulat %J International Journal of Advances in Engineering and Technology %D 2013 %I %X As UWB system transmit low power stream of short pulses in large spectrum ,their energy is spread over a large amount of spectrum .This signal can penetrate in noisy radio environment and provide high quality service for various application. In this paper the probability of symbol error for M-ary PAM and M-ary PPM is evaluated. For a given probability of symbol error data range performance of a reliable communication link is analyze using M-ary PAM and M-ary PPM modulation. The results are simulated using MATLAB %K Communication Systems %K UWB %K PAM %K PPM. %U http://www.e-ijaet.org/media/16N13-IJAET0313516-revised.pdf
