摘要
Abstract
In LTE systems,user equipment,when it is booted,will perform a cell search firstly. For the con-ventional cell search scheme,the integer carrier frequency offset( ICFO) and sector identity( ID) are jointly detected by utilizing the primary synchronization signal( PSS) . For this problem,this paper proposes a serial integer carrier frequency offset and sector ID algorithm. This algorithm makes use of the symmetry of the primary synchronization signal( PSS) and detects the ICFO and sector ID separately. Through normalized differential correlation of the received frequency domain PSS, the effect of channel is eliminated, thereby enhancing detection performance. Simulation comparison between the joint estimation algorithm and the proposed serial algorithm shows that the proposed algorithm can achieve better detection accuracy and the computational complexity is only 1/3 of that of conventional method.关键词
