Abstract | Full Text

The Transmitted-Reference (TR) is a technique used to improve the performance (gain) of received noisy multipath component in indoor and outdoor UWB signal. This technique is utilized by ultra-wide band (UWB) transceiver which receives very short transmitted pulses (less than 1 ns) using popular modulation and spread spectrum of time hopping. It is well-known that the inter pulse interference (IPI) is one of the most important challenges in transmitted reference impulse radio (TR IR-UWB) receiver. In this paper, a Modified-Hopped Single Delay (MHSD) TR receiver was proposed to completely remove the IPI drawback in TR and thereby increasing data rate and reducing Symbol Error Rate (SER) for better performance. This achievement requires a new modified 22-Hadamard matrix by using bi-orthogonal codes. The size of Hadamard matrix was then enlarged and tested. The results obtained in this study shows that a gain of about 2.7 dB has been achieved compared to conventional single delay (SD) TR receiver used in wireless techniques.
