This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication.


Platforms: Matlab

This script calculates the PSD of a time history. It prompts the user for parameters related to the spectral resolution and the number of statistical-degrees-of-freedom.


Platforms: Matlab

Let us assume the signal model:Y(k)=HX(k)+B(k)This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources. See reference [CHE91] Chen....

This script reads ROI files from ENVI by ITT DataVis into Matlab. It outputs a Struct to your Matlab session containing the ROIs by name and associated information according the the ROI file header. For each ROI, the struct includes the ROI name, color, number of points, and the ROI point matrix....
