Matlab code for BICM
Dear all I am implementing a soft input soft output (SISO) MMSE detector and SISO decoder in an iterative fashion (turbo receiver). A de-interleaver and interleaver is used in between the detector and decoder. I am using a convolution encoder at the transmitter side. Therefore, my decoder is the Log MAP decoder. I ... 6 Jan 2010 08:48

Locate Minima & Maxima
I am working on a project of calculating edge width in an image. I have to scan every row in the image to calculate the edge width. In order to do so, I need to detect several local minima and maxima for each row. An edge exists in between a local maxima and minima. There might be a few edges in one row. Any idea how t... 2 Feb 2010 15:23

Calculations involving Sparse Matrix
I am writing a function to reduce a large sparse matrix. The function is such that it takes a sparse matrix (say A) as its input and returns a sparse matrix (say B) which is half the size of the input matrix (along both axes) and the average of a neighborhood of 4 elements of A is the value of each element of B. For ex... 7 Jan 2010 06:50

Find parameters of PID for unkonwn transfer function of Plant and known reference.
Hi all, I want to know how to find PID parameters if we know the reference trajectory but the transfer function of Plant is not known. Manual tuning will obviously take time and I have tried a lot but unsuccessful. The Plant can't follow the desired trajectory. Is there any way of self-tuning or auto-tuning fo... 12 Jan 2010 18:33
