摘要
报道了一种用于差分双相相移键控/双相相移键控调制信号的声表面波扩频多符号检测器;基于声表面波,实现了直接序列扩频信号匹配滤波和多符号延迟差分解调的融合;研制了13位巴克码的4符号DBPSK/BPSK扩频多符号检测器,并对该检测器进行了实验测试和性能分析。
An Surface Acoustic Wave (SAW) multiple-symbol detector for DBPSK/BPSK spread spectrum was described. Based on SAW, the fusion of matched filter and multiple-symbol differential delay demodulation is implemented. The detector, which used this design for a 4-symbol differential detection of 13 bit barker code DBPSK/BSK spread spectrum signal, is tested and its performance is analyzed.
