Amplitude Modulation Matlab Code

Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength (amplitude) of the carrier in proportion to the waveform being sent. That waveform may, for instance, correspond to the sounds to be reproduced by a loudspeaker, or the light intensity of television pixels.

Amplitude modulation in matlab

The following Matlab project contains the source code and Matlab examples used for amplitude modulation. The codes in two files generate time and frequency domain representation of three basic types of amplitude modulation i>Double SideBand Amplitude Modulation (Full Carrier) (DSBAM) ii>Double SideBand Suppressed Carrier (DSBSC) iii>Single SideBand (SSB) The message signals used are combination of sinusoids of different frequency.

Color image compression decompression by using hybrid wavelet transform and cosine transform in matlab

The following Matlab project contains the source code and Matlab examples used for color image compression decompression by using hybrid wavelet transform and cosine transform. This Technique is very useful for the Programmer/Researcher/Users for color images compression type RGB. This Technique is using three level DWT and one-dimensional DCT.   

Kalman Filter Matlab Code

Kalman filter is an algorithm that uses a series of measurements observed over time, containing noise (random variations) and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone.

kalman filter

Kalman filter in matlab

The following Matlab project contains the source code and Matlab examples used for kalman filter. This function performs Kalman filtering on data consisting of two variables. A constant-velocity model is assumed. The filtered output and the error from the ground truth is computed. Comments are welcome.
