Orthogonal beamforming for overlay mode of OFDMA-based rural broadband wireless access

Jinho Choi, Jeongseok Ha · 2012

Summary. This paper proposes an overlay mode for OFDMA-based cellular systems that delivers broadband wireless access to rural users without interfering with urban mobile users. Using orthogonal beamforming, the system constrains signals to rural users to remain orthogonal to channels serving higher-priority mobile users. The authors demonstrate that rural users achieve acceptable signal-to-interference-plus-noise ratios despite these constraints, making the approach viable for rural broadband deployment.
