Abstract
In this paper, the signal-to-interference-plus-noise ratio (SINR) analysis of orthogonal frequency-division multiplexing (OFDM) systems over the IEEE 802.15.3c 60 GHz channel models is investigated. The derivation precisely captures the distinctive path clustering phenomenon in the spatial-temporal domain and provides the exact SINR. Based on the analytical results, a universal rule for adapting the near-optimal half-power beamwidth is identified. Moreover, numerical results are provided to verify the analytical findings. © 2012 IEEE.
