LJ_to_Morse

说明：  matlab仿真LDPC码，对采样点数进行PPM编码，此代码加了保护时隙(The LDPC code is simulated by matlab, and the sampling points are encoded by PPM, which adds protection time slot.)

说明：  讨论了变换域通信系统中收发端一致时的系统性能，包括AWGN信道及单音，多音，窄带，扫频干扰(Discussed the transform domain communication system is identical to sending and receiving end system performance, including the AWGN channel and the tone, multi-tone, narrowband, swept-frequency interference)

此编程是对于平方解调和希尔伯特解调分析的展示，希望能够帮到大家(This programming is for the square demodulation and Hilbert demodulation analysis of the show, hoping to help everyone)

TI TMSC6713 DSP 实现 OFDM的调制和解调，以及相应的matlab功能仿真程序。(TI TMSC6713 DSP realization of OFDM modulation and demodulation, and the corresponding function matlab simulation program.)

说明：  matlab编写的FDTD（时域有限差分法）程序，可以实现完整天线方向图和反射系数的计算，以贴片天线为例，对比了编写程序的反射系数与方向图和HFSS计算的反射系数与方向图，具有一致性。(FDTD (finite difference time domain) program compiled by Matlab can realize the calculation of complete antenna pattern and reflection coefficient. Taking patch antenna as an example, the reflection coefficient and pattern calculated by the program and HFSS are compared, which are consistent.)

说明：  基于均匀线阵的强干扰条件下弱信号的DOA估计，采用MUSIC算法(Based on the DOA estimation of weak signal under strong interference of uniform linear array, music algorithm is adopted)

mapx4.5，程序不大，可以用，内部没有地图，矢量地图要仔细，里面没有地图(Mapx4.5, program is not big, can be used, internal without maps, vector map carefully, there is no maps )

能在大规模场景下，运行的slnr预编码算法(SLNR precoding algorithm for running in large scale scenes)
