characteristic-function

功能：该程序用于仿真时间同步算法双向不等时间同步方法（TWT-UTD）与无时漂往返校时方法（RTT）。输入：节点间距离、钟漂，输出：两幅同步误差比对图。(Features: The program for the simulation time synchronization method of time synchronization algorithm for two-way ranging (TWT-UTD) and no drift from the time when the method of school (RTT). Input: the distance between nodes, clock drift, output: 2 synchronization errors of the map.)

Non-Causal IIR Filter Part 1: Setting up the Input signal to the Wiener Filter Part 2: Seperating the negative lags and positive lags... The one at 0 index is clustered together in the positive part highqq

The simulation is a wideband signal is white noise with variance 0.05, single frequency to the frequency of the signal for a single frequency signal 2 to 2 times the adaptive filtering simulation

This function is a very simple application of FFT2 for an image to simulate the effect of bandpass filter with two cut off frequencies. One can easily modify the programme to do the processes for different images, and even implement highpass and lowpass filter
