Performance Analysis of OFDM Systems Over 60 GHz Indoor Channels
Owing to the great demand on high-speed wireless communications in short-range environments, 60 GHz communications have attracted considerable interests,. IEEE 802.15.3c is one of the important wireless standards operating in the 60 GHz band. 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 beam-width is identified. Moreover, numerical results are provided to verify the analytical findings.
