摘要
基于简化后的ML(最大似然)估计算法,提出一种适用于TD-LTE(时分长期演进)系统的时频同步算法,并在TMS320C64x DSP(数字信号处理器)中实现了该算法。仿真结果表明,该同步算法在不同的信道环境下都能较好地工作,具有稳定、计算复杂度低等优点。
On the basis of the simplified Maximum Likelihood（ML） estimation algorithm,a novel time and frequency synchronization algorithm for the TD-LTE systems is proposed and realized in the TMS320C64x Digital Signal Processor（DSP）.Simulation results show that this algorithm is characteristic of stability and low computation complexity and can work well in different channel scenarios.
