The physical (PHY) layer of ZigBee communication systems was defined by IEEE 802.15.4 and has good external white noise resistance due to its spread spectrum characteristic and error correction of the baseband coding process. However, previous research has shown the performance of ZigBee to degrade in the presence of impulsive noise. In this regard, an improvement of the ZigBee receiver is warranted...
This research focuses on improving the performance of ZigBee-based wireless communications in high impulsive noise environments such as those found in power utility and manufacturing facilities. Previous research has shown the physical layer used by the ZigBee standard to be vulnerable to impulsive noise due to its wide frequency spectrum and high energy content. Hence, our goal is to develop a novel...
Orthogonal frequency division multiplexing (OFDM) can be susceptible to impulsive noise arising from numerous sources in a noisy communications environment. Conventional Reed–Solomon (RS) codes are particularly useful for burst-error corrections and have been employed in OFDM systems to manage impulsive noise. The performance gains, however, have been somewhat limited given the sensitivity to other...
An investigation of the performance of ZigBee systems in high voltage electricity substations is described in this paper. The ZigBee wireless platform is a cost-efficient wireless networking system recently for the purpose of monitoring substation components in electric substations. Although this system has some inherent resistance to interference given its spread spectrum technology, impulsive noise...
