摘要
针对Schmidl定时同步算法中出现的峰值平台和H.Minn定时算法中出现的多个副峰值等问题,提出改进算法的训练序列结构的思路,当定时时刻在循环前缀范围内,循环前缀中样值的相关运算对总的求和表现为减少,能消除峰值平台,减轻多峰值的影响.仿真结果表明改进后的算法消除了Schmidl的峰值平台和H.Minn的多个副峰值,提高了系统定时的性能.
The thought of improving Schmidl algorithm is proposed in the article to overcome the peak value plateau which occurs in the algorithm and multi-peak value which occurs in H.Minn algorithm. When the timing is in the range of circulation prefix, the total sum of related calculation is reduced, which can eliminate peak value plateau and reduce the influence of multi-peak value. Simulation results show the improved algorithm has better performance than than Schmidl algorithm and H.Minn algorithm.
