- Fast Circular (Periodic) Cross Correlation
- License: Freeware
- Price: 0.00

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal). The package also includes two examples.

- implementation of digital pulse compression using matlab
- License: Freeware
- Price: 0.00

In Radars, range resolution and long range of operation are the two important aspects. Long range operation means the maximum distance over which radar can detect the targets. The radar transmit modulated pulses to take the advantages of better processing gain and resolution of these waveforms are compared to continuous wave pulse.

The AudioDevice blocks that ship with Signal Processing Blockset utilize the PortAudio library to communicate with the audio hardware. Although the PortAudio library supports a range of API's designed to communicate with the audio hardware on a given platform, the following choices were made for the version of PortAudio that is built for Simulink: Windows: DirectSound Linux: OSS Mac: CoreAudio If you wish to enable communication between Simulink and your audio device using a different API, it is possible to build your own version of the PortAudio library and use it in place of the PortAudio library that ships with the Signal Processing Blockset.
