The incoherently demodulated spread spectrum modem with bandwidth of 4 MHz and data rate of 32 kbit/s uses PN sequence phase-coded SAW tapped delay lines(SWTDL)with center frequency of 32 MHz as the phasecoded waveform generator and matched filter.

• 表面波抽头延迟线非相干扩频调制解调器使用m序列相位编码表面波抽头延迟线作为相位编码波形发生器和匹配滤波器。 它具有4MHz带宽和32kbit/s的数据率。
