1. Sparse Approximation of Spatial Channel Model with Dictionary Learning
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In large antenna systems, traditional channel estimation is costly and infeasible in some situations. Compressive sensing was proposed to estimate the channel with fewer measurements. Most of the previous work uses a predefined discrete Fourier transform matrix or overcomplete Fourier transform matrix to approximate the channel. READ MORE
