利用matlab设计带通滤波器。很实用。编译通过。思路来自期刊论文(matlab bandpass filter)

此算法是著名的流行学习算法，可以用于数据特征的提取，维数约减等操作。(This algorithm is a famous and usefule algorithm for extrating the fature or reducing the dimension.)

this file have simple demodulation program for qpsk demodulation. it will give the bit of stream after demodulation of qpsk (quadrature phase shift keying) wave.

this code implementation fir filter.

RNNSIM ver. 1.0 is a program with an intercative graphical user interface (GUI) that runs under MATLAB ver. 5.0 or higher. The program can be used in training and testing the Random Neural Network(RNN) models. This version (ver. 1.0) implements only the 3 layer feed forward RNN model. In the next versions, the multi hidden layers and the recurrent RNN models can be implemented. To obtain faster training, the training section can be written as a MEX file and invoked from the GUI. If you have the m files in the directory rnnsim for example, then you can run the program following the next steps: 1- run MATLAB as usual 2- from the MATLAB command window, write cd rnnsim 3- from the MATLAB command window, write rnnsim

The statements below guide us to write the code for the transmission of sensed data to a sink node using cognitive radios in multiple spectrum bands. In doing this we are trying to find the most appropriate modulation scheme using MATLAB simulation.
