Abstract
In this paper, we propose a pilot reuse scheme based on partial access points (APs) for the performance of the uplink link level. Considering the interaction between pilot reuse and channel gain, this scheme proposes the concept of minimizing the sum of the normalized errors of the estimated channel between the user and selected APs and suppress intral channel interference of user groups using non-orthogonal pilots. The scheme’s performance is reflected and analyzed by the uplink rate, and the simulation results show that the proposed scheme has achieved remarkable results compared with the existing schemes.
