Abstract

一种数据信道的解扰解扩装置，该装置包括：码片旋转及相关电路，设置为：根据码片偏移量chip_offset，用S个二选一开关从2S个码片天线数据ant_data0~ ant_data(2S-1)中选取参与相关累加的S个码片天线数据，然后将该S个码片天线数据与伪随机码做相关操作，输出相关后的S个码片Chip0~Chip(S-1)，其中，S=2X ，0<=chip_offset<S，S、X、chip_offset均为正整数；码片累加及旋转电路，设置为：根据扩频因子SF对Chip0~Chip(S-1) 中的相邻SF个码片进行累加，且在累加过程中对码片作旋转，得到正确排序的 S个码片的相关累加结果，其中，SF=2 j ，j均为正整数。上述装置可以减少数据信道的解扰解扩所需多路选择器，减小实现面积。
