Abstract
Massive Multi-Exit Input (MIMO) devices are required to handle the enormous number of matrix inversion operations during signal detection. When dealing with massive MIMO systems, there are a number of alternatives that can be used to avoid an exact matrix inversion. Two types of signal detection techniques are first introduced in this research. The association is then established using a Newton iteration technique. Minimize computing complexity by converting matrix-matrix products into matrix-vector products. This is another way to reduce computing complexity. That numerical simulation can beat Neumann series expansion and Newton method in a few rounds is also demonstrated.
