this code is finite diffrence method

估算在给定门限下常用输入信号的带宽。函数将代表待分析波形的矢量signal作为输入(estimate in a given threshold under the common input signal bandwidth. Function will be representative of the waveform analysis as input vector signal)

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

CIC filter setup, this is special used for the DDC

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)

segmentation tool to enable segmentation of images, either simple jpegs or other image

Boid模型的matlab代码，仿真鸟类的情况，可生成动画。(The matla code of a boid model to simulate the bird flying ,which could be used to set up a*.avi animation.)

this is very useful file that simulate the memory polynomial method.
