Gaussian Calculationsd

Calculate and plot BER curve against SNR for BPSK Modulation in Gaussian Environment.It calculates 100 errors to Calculate BER for every SNR value to ensure better approximation.I hope that this help students of signal processing and communications alot.

Carries out Gaussian smoothing followed by differencing as a way of estimating the gradients of a grey-level image in the X and Y directions. This is the initial stage of the well-known Canny edge detector, but the gradients can be used for many other applications.The function offers independent...

NDGAUSS: create ND gaussian kernel in any derivative order. g = ndgauss(hsize,sigma); [g,xi,yi,..] = ndgauss(hsize,sigma);Inputs: - hsize is N-length of kernel size. - sigma is N-length of standard deviations (gaussian widths).Outputs: - g is the kernel. The size of g is hsize(1) x hsize(2) x ......

Auto Gaussian & Gabor Surface fit---2 functions to fit a 2D Gaussian or 2D Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit (sum of squared error) for...
