数字基带信号的调制与解调的matlab程序(matlab of the)

针对传统线性调频(LFM)信号参数估计算法中复杂的搜索和计算问题，提出了一种不需要参数搜索的快速 LFM信号参数估计算法。该算法先用希尔伯特变换估计LFM信号瞬时相位，再用二次相位函数拟合LFM信号瞬 时相位从而得到初始频率和调频斜率的估计(The traditional linear frequency modulation (LFM) signal parameter estimation algorithms and computational complexity of the search problem, we propose a fast search without LFM signal parameter estimation algorithm. The algorithm first estimated with the Hilbert transform of LFM signal instantaneous phase, and then the second phase of LFM signal instantaneous phase function fitting to obtain the initial estimates of the frequency and chirp rate)

在光纤通讯仿真中，产生QPSK，16QAM，64QAM信号，并添加激光相位噪声和自发辐射噪声(In optical fiber communication simulation, QPSK, 16QAM, 64QAM signals are generated, and laser phase noise and spontaneous radiation noise are added.)

数字基带信号通过瑞利信道（rayleichangh），在多径时延的条件下，通过自相关函数看其时延大小。(Digital baseband signal by Rayleigh channel (rayleichangh), under conditions of multipath delay, the autocorrelation function of the delay size.)

（九宫问题）在一个３×３的九宫中有１－８这８个数及一个空格随机的摆放在其中的格子里，如图１－１所示。现在要求实现这个问题：将该九宫格调整为如图１－１右图所示的形式。调整的规则是：每次只能将与空格（上、下、或左、右）相邻的一个数字平移到空格中。试编程实现这一问题的求解。((Nine-palace issues) in a 3 × 3 of the Nine-palace are 1-8 this 8 random number and the placing of a space in which the cell house, as shown in Figure 1-1. Now required to achieve this issue: the squares adjustment for the right as shown in Figure 1-1 form. Adjustment of the rules: each can only be with the spaces (upper and lower, or left, right) adjacent to a digital flat space. Test Programming to solve this problem.)

UWB_Channel_IEEE_802_15_3a.rar是用MATLAB对UWB信道进行仿真的实例，所仿真的信道是UWB的标准信道模型。(UWB_Channel_IEEE_802_15_3a.rar is used for UWB channel MATLAB simulation examples, the channel simulation is the standard UWB channel model.)
