A New Power Control Algorithm in MMSE Receiver for D2D Underlying Massive MIMO System

Device to device (D2D) underlying massive MIMO cellular network is a robust deployment which enables enhance its throughput. It also improves services and applications for the proximity-based wireless communication. However, an important challenge in such mutual interference. Interference, uplink spectrum, reusing same resource with user, caused by D2D users. In this paper, we study distributed power control (DPC) algorithm, using minimum mean square error (MMSE) filter receiver, mitigate produced interference scenario. For DPC employing coverage probability of links, optimal approach proposed, maximizes spectral efficiency links. Using modeling approach, it possible derive closed-form analytical expressions probabilities ergodic efficiency, give insight into how various parameters interact affect link.‎ Also, algorithm modeled stochastic geometry receiver designed estimation theory that new structure improve efficiency. Simulation results illustrate enhancing performance links term target (signal ratio) SIR respect different other are existing
