摘要:
提出了能应用于未来移动通信系统的基于插值二维能量窗同步算法及其硬件实现.算法通过对2倍采样信号进行插值,从而以较低的实现复杂度得到较高的同步精度; 通过对多个接收通道的同步序列相关值进行非相干合并,充分利用了空间分集,从而大大减轻了衰落的影响; 通过对多径分量的能量进行合并,然后在合并后的判决变量上进行判决,充分利用了宽带无线通信系统中的多径信号能量,进一步减轻了衰落的影响.仿真表明,算法具有很好的性能.该算法已应用到B3G实验系统中.实验表明,该算法能提供精确的定时,以保证实验系统的正常工作.
Abstract:
Through interpolation on 2-fold sampled sequence, high synchronization accuracy can be obtained with lower complexity; through non-coherent combining of correlator outputs from different receive antennae, spatial diversity is achieved, and the effect of fading is alleviated; through combining of the energies carried on different multi-path components, the effect of fading is further alleviated, and thus leading to robustness in fading channel. Simulations show its good performance. The synchronization scheme is implemented using field programmable gate array(FPGA)and adopted in the B3G experimental system. Experiments show that it can provide high accuracy timing.
