Differential PSK (DPSK) 􀂄 Inexpensive 􀂄 Quadrature Phase Shift Keying (QPSK) 􀂄 Twice as spectrally efficient than BPSK 􀂄 Offset QPSK (OQPSK) 􀂄 reduce envelope variation 􀂄 π/4 QPSK 􀂄 reduces envelope variations to a lesser extent than OQPSK can be noncoherently detected

c++实现的通信录，实现添加、删除、查找、修改等功能(communications recorded c++ implemented add, delete, search, modify functions)

数字调制信号与仿真的书本中的第四章节的MATLAB仿真代码，需要的话可以跟我联系取得其他章节的代码(And simulation of digital modulation signals in the fourth chapter of the book MATLAB simulation code, you need to contact me if you can obtain the other chapters of the code)

说明：   Matlab file for simulating a cyclic-prefix (CP) orthogonal-frequency-division-multiplexing (OFDM) system with binary phase-shift keying (BPSK) modulation on each subcarrier. CP-OFDM system includes a repetition code and interleaving across subcarriers as well as a Rayleigh-fading channel model with exponentially decaying power profile.

DFT和FFT的matlab实现及算法差异的证明，如复杂度等。（精度、不同长度的序列等）。(DFT and FFT algorithm matlab realize the difference and proved as complex and so on. (Accuracy, sequences of different lengths, etc.).)

matlab的一些文件，很好的东西哦，希望对大家有助。(matlab some documents, good things Oh, I hope to help everyone.)

说明：  MUSIC算法；是平面阵的。很好用。大家交流学习(MUSIC algorithm is planar array. Good use. To facilitate the exchange of learning)

用四元十字阵做被动声定位算法设计，现在是用matlab神经网络工具箱构建RBF神经网络然后仿真显示图形(With a four-element Array do passive acoustic localization algorithm design, now using matlab neural network toolbox and then build on RBF neural network simulation display graphics)

数字相控阵雷达fft多波束形成算法，简单易懂(Digital phased array radar fft multi-beamforming algorithm, easy to understand)
