Abstract

Novel statistical channel models based on tapped-delay lines are proposed for the evaluation of indoor millimeter-wave wireless communication systems. The considered frequency bands for its application are around the 62.5-GHz region for wireless personal area networks. The channel characterization was carried out inside a conference room environment with fixed communication links. The proposed models acquire the significant paths in the propagation channel that are necessary to achieve high gigabit-per-second throughput by using directive (high-gain) antennas that emulate the radiation pattern of beamforming antenna systems. The anticipated application is for simulating wireless systems inside conference rooms under line-of-sight (LoS) conditions, and under non-LoS conditions wherein the transceiver seeks the candidate signal path among the reflected waves and then switches to the best signal-to-noise ratio path so that a high-rate link could continue. As indicated by the modeling results, only several paths are useful for very high speed communication rates. These paths and the effects they bring to the receiver, like delay spread, are taken into account by the proposed millimeter-wave channel models.
