使用matlab确定迭代搜索区间,与进退法稍有不同(use matlab for search bound)

A Matlab code to simulate an OFDM with zero padding

MUSIC算法是最经典的超分辨DOA估计方法，它利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA。MUSIC算法对DOA的估计从理论上可以有任意高的分辨率(MUSIC algorithm is the most classical super-resolution DOA estimation method. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectral function, and detects the DOA of signal through peak search. MUSIC algorithm can theoretically estimate DOA with arbitrary high resolution.)

FIR滤波器的一种设计实现，给出了详细的源代码，和原理。(FIR filter design and implementation of a given source code in detail, and principles.)

LDPC仿真程序,采用log-BP算法 (LDPC simulation program using the log-BP algorithm)

matlab代码 迭代法求解非线性方程 用不动点迭代法求非线性方程组的一个根(matlab code iterative method for solving nonlinear equations using fixed point iteration method for solving nonlinear equations of a root)

采用MORISON方程基于MATLAB计算小直径波浪力(small diameter waveforce)

改进等高线拟合代码，很有价值。(improve contour fitting code and of great value.)

CA码生成程序。可以产生32颗卫星的。并载波，采样(CA key generation procedures. Can produce 32 satellites. And the carrier, sampling)

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
