希捷指令集，里边详细的介绍了希捷12代的指令等。(Seagate instruction set inside a detailed introduction of 12 generations of Seagate directives.)

说明：  c++源程序代码 c++源程序代码(source code c c c source code source code)

说明：  产生随机信号，采用4fsk调制方式通过一个水声信道，再采用非相干解调(Generate random signal, use 4FSK modulation to pass through an underwater acoustic channel, and then use incoherent demodulation)

这个是关于OFDM系统的信道估计的算法的两种方法，分别是OFDM的最小二乘和最小均方误差估计的仿真程序代码(the OFDM system is on the channel estimation algorithm of the two methods OFDM are the least squares and minimum mean square error estimate of simulation code)

说明：  基本的调制解调程序集(包括BPSK,QPSK,QAM,GMSK等) 基本的调制解调程序集(包括BPSK,QPSK,QAM,G(Basic modulation and demodulation assembly (including BPSK,QPSK,QAM,GMSK, etc.) basic modulation and demodulation assembly (including BPSK,QPSK,QAM,G))

用于变电所的电力103通信测试的源代码,主要用在工控行业(103 for electricity substation communications test source code, mainly used in the industrial sector)

低信噪比条件下的高分辨DOA估计算法,提出一种基于多级维纳滤波器(MSWF)的信号波达方向(DOA)估计算法。通过测试信号子空间的估计值与噪声子空间的正交性实 现 DOA粗估计，通过测试MSWF 分解的互相关函数实现信号 DOA 的精估计。仿真实验表明，在低信噪比条件下，该算法比已有的子空 间类算法有更好的分辨率和误差性能。(Put forward a kind of multistage Wiener filter (MSWF) based on the signal direction of arrival (DOA) estimation algorithm. By testing the orthogonality between the estimated values of the signal subspace and the noise subspace Now DOA coarse estimation, by testing the MSWF decomposition of the cross-correlation function to achieve accurate estimation of signal DOA. Simulation results show that the proposed algorithm is more efficient than the existing subspace in low SNR conditions The inter class algorithm has better resolution and error performance.)
