simulation of optic fiber link budget analysis is to feed input as attenuation loss, connection loss , system margin, transmitted power and length of the fiber

Makes a simple avi movie from a sequence of frames The user can control the display time of each frame. The movie is created in the same folder where this function is run. Usage: Inputs: name: root name of the framse filetype: .bmp , .jpg , .jpeg , .tif ,,,, number_of_frames: number of the frames display_time_of_frame: it is the display time of each frame Output: it creates a file named as Movie.avi in the same folder of this function

kalman filter program...extended kalman filter

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
