| 摘 要： | 为了增加正交频分复用(OFDM)小区识别的数量,同时保持小区搜索的性能,设计了一种新的OFDM小区搜索方案.其核心思想是在载波上先加载称为"子载波模板"的伪随机序列,然后再加载频域差分序列.针对这种新的结构,该方案还设计了一种联合估计算法,可在性能保持不变的情况下,增加10~20倍识别小区的数量.

| Abstract: | In order to increase the OFDM cell identification numbers as well as remain the cell search performance,a new scheme was proposed.The core idea is that the 'sub-carrier mask index' is loaded before differential sequence is modulated on the sub-carrier.A jointly estimating algorithm is designed to improve the performance so the proposed scheme can identify 10 to 20 times the call identification numbers of the traditional scheme. |
