Wireless sensor networks (WSNs) powered by energy harvesting is a promising technology for monitoring and diagnostic systems in smart grid. However, the limitation and instability of harvesting energy leads to the requirement of high energy-efficient time synchronization algorithms for WSNs. In this paper, in order to minimize the energy consumption, we propose an improved hybrid time synchronization...
Abstract-This paper addresses the real-time demand of radix-4 FFT processor in modern digital signal processing domain. Full parallel and pipelined architecture can be a good solution while too much hardware is consumed. Therefore a useful optimization method of complex multiplier and twiddle factor which has been successfully used to implement the FFT algorithms achieving a reduction in multipliers'...
