Abstract:
This paper focuses on a low-cost synchronization technique based on power criteria for impulsive ultra wideband scheme applied to power line communication systems. The advantage offered by this technique is that the knowledge of both channel pulse response and noise information are not required. To assess the proposed technique, we discuss performance results obtained with typical in-home, outdoor, and low-voltage power line channels covering the frequency band between 1.7 and 50 MHz and additive noises modeled as white Gaussian and impulsive Gaussian. The results show that the proposed technique achieves the best performance in terms of detection probability, false alarm probability, and bit error rate in comparison with previous synchronization techniques, which were design to work with the aforementioned data communication system. Besides, implementation analysis on field programmable gate array shows that the proposed technique demands less hardware resource utilization than previous techniques and its finite word length implementation with at least 16 bits word length results in negligible performance degradation.
