ABSTRACT CDMA Timing and phase offsets tracking remain as one of considerable factors that influence the performances of communication systems. Many algorithms are proposed to solve this problem. In general, these solutions process separately the chip sampling offset and phase rotation. In addition, most of proposed solutions can not assure a compromise between robustness criteria and low complexity for implementation in real time applications. In this paper we present an efficient algorithm for chip sampling and phase sync...

ABSTRACT In the current economic and political scenario of Pakistan where new projects of Electrical generation seems impossible, one should adopt such means so as to minimize the power consumption via load management. In this paper a relatively better Electrical power system is proposed for University of Gujrat (UOG) power system. UOG runs its all generators whether it is full load or merely a load of 20 percent as a standby power. It is su...
