... performance. The demand for higher data rates over the past decade drives the rapid development of mobile and wireless communication systems (Cox, 2008). Orthogonal frequency division multiplexing (OFDM) is a key technology used in many wireless and wireline communications systems. Most modern digital...

...TianQuan James Deng; Lei Lin; De‐kai Xu; Hou‐jun Wang Purpose The purpose of this paper is to provide a new method of the fault diagnosis of wireless sensor networks (WSNs) node, which is based on wavelet neural network (WNN). Design/methodology/approach The approach uses WNN to diagnose...

...TianQuan James Deng; Qiangyu Zeng; Xiaohai He; Rui Lv; Wei Wu Purpose The purpose of this paper is to introduce an efficient rate control algorithm for the H.264/AVC video coding in wireless communication. The adaptive rate control algorithm can reduce rate fluctuation, effectively prevent...

...TianQuan James Deng; Shuangmao Yang; Wei Guo Purpose The purpose of this paper is to introduce the performance of traditional collision resolution algorithm (CRA) under self‐similar traffic and present a prediction‐based CRA for wireless media access. With experimentations, the method...

...TianQuan James Deng; Tansheng Li Purpose The purpose of this paper is to present a wireless sensor network system which can monitor human physiological signals of heartbeat rate and body temperature. Design/methodology/approach When physiological activity occurs, signals are generated...
