Code in Python for an OMP and SVD algorithms to reduce the dimensionality of a matrix

This is a mini project to compress channel matrix H in Wireless communication. The channel matrix 'H' is obtained from a library called HermesPy. I have attached a sample code on how to generate the Matrix. Task is to implement OMP and SVD algorithms to compress the matrix and reduce the dimension of channel matrix without loss of Data. The idea is to reduce the overhead of this Matrix which has to be sent as a feedback to Base Station in 5G wireless communication
