The AWGN Channel Block in the Communications Blockset lets you specify SNR in several ways, including Eb/No. Sometimes people want to use a more itemized way of specifying the SNR, like the itemization found in a link budget. These two models show how to create equivalent implementations of a communication channel, one using the AWGN Channel block and the other using specifications for Transmitter Gain, Antenna Gain, Path Loss, and Receiver Noise Temperature.

This package consist of a number of auxiliary functions that are helpful for analysing 1D and 2D signals such as surface profiles and surfaces and images. They are all built upon the built-in MATLAB FFT routine for fast execution and they replicate (when it is existing) the result produced by built-in MATLAB function to some extent or completely.

  • Platform: Matlab, Scripts

With this Fourier Calculator a periodic signal can be analyzed and represented in figures with harmonics. The signals can easily be produced in the model..

This mex file implements vectorized FFTs on multiple threads. When a matrix is passed to FFTmt, it is divided in "numCPU" and each fraction of the problem is executed in a separate thread Example: if numCPU = 2 and the matrix has 256x2^14 elements, 128 FFTs are performed in each thread, allowing the OS to distribute the load on 2 processors.

After the run of the "MyEqualizer.m" file a graphical user interface appear. By pressing the "Load" we can load audio signal (type .wmv). After we can model the frequency behavior of the FIR filter that is used to filter that signal. After we can listen the filtred audio signal by pressing the "Play " button.

"According to the U.S. National Highway Traffic Safety Administration, single-vehicle road departures result in many serious accidents each year. To reduce the likelihood of a vehicle's straying out of lane, automotive engineers have developed lane tracking and departure warning systems that use a small camera to transmit video information about lane markings and road conditions to a microprocessor unit installed on the vehicle.
