  • 摘要:Based on recent research about UWB communication, its clearly that one of the most interesting feature of the Pulse-based UWB technology is it�s high flexibility in term of the generated signal at the physical layer level. This feature combined with simple transceiver as it is almost digital communication structure allows this technology to be a good solution of different short-range wireless applications. This paper proposes enhancements on the receiver performance by tuning the most important physical parameters of the generated pulses as pulse modulations, coding and frame timing structure as these parameters are in great influences on the performance of the receiver. This performance can be defined as the probability of the lost packet in certain signal to noise ratio in varied distances and data rate scenarios. The method followed to validate the achievements of the enhancements of the receiver performance can be explained as proposing a communication link of certain pulse-based wireless system where at the beginning the physical parameters are set as reference parameters then the performance of the receiver measured. After that, tuning each parameter separately to check the enhancements of the receiver performance in certain different data rates an distances. Results showed that the performance can be enhanced significantly in term of the received signal errors for certain signal noise to power ratio with approximately up to 50% by tuning some physical parameters that have significant effects on received signal quality.
