Calculating Correlation Coefficient

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment.It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER.I hope this will help students alot.Please feel free to contact me should anyone has any queries.

Develop a Matlab program to demonstrate a neural network autoassociative memory. Show the importance of using the pseudoinverse in reducing cross correlation matrix errors. Show the performance of the autoassociative memory in noise. The results are contained in the Matlab file assoc_mem_demo.m

Method 1 . Using Step Response and Delay Time and Time Constant Parameters.Method 2 . Using proportional controller action only. you should find critical gain and corresponding critical period.all results come in 2 different output shape.1- Controller with (Kp - Ti - Td)2- Controller with (Kp -...

Let us assume the following MIMO model:Y(k)=HX(k)+Y(k)This file can detect the number of sources, i.e the size of the vector X(k) from the received signal Y(k). The noise is assumed spatially white and the number of receivers must be strictly greater than the number of sources. For more details...
