We propose an analytical stochastic geometry-based model for multiple-input multiple-output (MIMO) heterogeneous cellular networks (HetNets) with zero-forcing (ZF) precoding at transmitting base stations (BSs) and partial zero-forcing (PZF) beamforming at receiving user equipments (UEs). The user and area spectral efficiencies are characterized using a non-direct moment- generating-function (MGF)...
Characterizing the fundamental energy efficiency (EE) performance of multiple-input–multiple-output interfering broadcast channels (MIMO-IFBC) is important for the design of green wireless system. In this paper, we propose a new network architecture proposition based on EE maximization for Multi-Cell MIMO-IFBC within the context of interference alignment (IA). Particularly, EE is maximized subject...
