QPSK123

Kasami序列产生器 用于扩频通信(Kasami sequence generator for spread spectrum communications)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)
