Analysis of the Rician K Factor in a Typical Millimeter-Wave Office Scenario
[EN] In this letter, the K-factor is estimated in a typical office scenario based on wideband channel measurements carried out at millimeter-wave (mmWave) frequencies, covering the 25-40 GHz spectrum, in both line-of-sight (LOS) and obstructed-LOS (OLOS) propagation conditions. The K-factor is estim...

| Sumario: | [EN] In this letter, the K-factor is estimated in a typical office scenario based on wideband channel measurements carried out at millimeter-wave (mmWave) frequencies, covering the 25-40 GHz spectrum, in both line-of-sight (LOS) and obstructed-LOS (OLOS) propagation conditions. The K-factor is estimated from the method of moments, applied directly over the frequency samples of the measured complex channel transfer function, and from the power delay profile-based method. Although both methods provide similar results, the method of moments is more appropriate from a practical point of view, especially in OLOS and non-LOS (NLOS) conditions, where the correct identification of dominant components can be difficult. The results are particularized to the potential 26, 28, 33, and 38 GHz frequency bands for the design and deployment of the future wireless networks at mmWave frequencies. The mean value of the K-factor ranges from -1.87 to 1.27 dB for the LOS condition, and from -3.79 to -2.31 dB for the OLOS condition. |
