Learning-Based Coexistence in Two-Tier Heterogeneous Networks with Cognitive Small Cells
Lin Zhang, Guodong Zhao, Wenli Zhou +3
We study the coexistence problem in a two-tier heterogeneous network (HetNet) with cognitive small cells. In particular, we consider an underlay HetNet, where the cognitive small b…

Estimating the Distance Between Macro Base Station and Users in Heterogeneous Networks
Lin Zhang, Wenli Zhou, Wanbin Tang +2
In underlay heterogeneous networks (HetNets), the distance between a macro base station (MBS) and a macro user (MU) is crucial for a small-cell based station (SBS) to control the i…

Primary Channel Gain Estimation for Spectrum Sharing in Cognitive Radio Networks
Lin Zhang, Guodong Zhao, Wenli Zhou +4
In cognitive radio networks, the channel gain between primary transceivers, namely, primary channel gain, is crucial for a cognitive transmitter (CT) to control the transmit power…
