doa

doa, a MATLAB code which tries to determine the direction of arrival (DOA) from which narrow band electronic signals are arriving at an array of pairs of sensing stations. This code is derived from Dianne O'Leary's "Scientific Computing with Case Studies".

The data involves 720 observations of two signals. The data file stores both the complex signal data X and the matrix of true angles THETA measured in degrees. The signal data X has been perturbed by a normally distributed random error with mean 0 and stardard deviation of 1.
