| 摘 要： | 本文介绍了用于ＤＰＳＫ调制的ＤＳ扩频信号非相干检测的一种ＳＡＷ器件的设计方法。对所研究的差分延迟功能均集于单一器件中。因为没有采用独立的延迟线，故消除了带限影响，ＤＰＳＫ解调器延迟支路无插入损耗。

| Abstract: | In this paper,we introduce the design method of a surface-acoustic-wave component for the noncoherent detection of direct-sequence spread-spectrum signals with a differential phase-shift keying (DPSK)modulation format.In the considered DifferenfialDelay function are merged into a single device.Due to the absence of a separate delay line,neither bandwidth-limiting effects nor high insertion losses in the delay branch of the DPSK demodulator. |
