Modify the Gray-coded modulation example (COMMDOC_GRAY)
so that it uses a pair of square root raised cosine filters
to perform pulse shaping and matched filtering at the
transmitter and receiver, respectively.
Description The MUSIC algorithm, proposed by Schmidt, first estimates a basis for the noise subspace and then determines the peaks the associated angles provide the DOA estimates.
The MATLAB code for the MUSIC algorithm is sampled by creating an array of steering vectors corresponding to the angles in the vector angles.
