摘要 基于Ranging码的频域相关性,针对IEEE802.16e标准的OFDMA系统,提出了一种时频结合的初始Ranging检测算法,通过调整两门限的设置,在保证较高的检测性能基础上,可以有效地检测接收信号中有无Ranging请求、Ranging码编号、时偏等信息并且减少了Ranging检测的计算量。 Based on the ranging code＇s correlation in frequency domain,a time-frequency ranging detection algorithm for initial ranging of OFDMA systems in IEEE802.16e standard is proposed,which not only guarantees high detection performance through adjusting two thresholds,but also effectively detects a ranging request,the number of ranging code and time offset and reduces the ranging calculation.
