Computationally Efficient Channel Estimation in 5G Massive Multiple-Input Multiple-output Systems

Computationally Efficient Channel Estimation in 5G Massive Multiple-Input Multiple-output Systems

Traditional channel estimation algorithms such as minimum mean square error (MMSE) are widely used in massive multiple-input multiple-output (MIMO) systems, but require a matrix inversion operation and an enormous amount of computations, which result in high computational complexity and make them im...
