Statistical Characteristics of 60 GHz Wideband Indoor Propagation Channel

Abstract

This paper presents statistical properties of the space-time propagation channel at 60 GHz. An extensive measurement campaign is conducted for three different type of corridors in an office building. The 60 GHz channel sounder used is capable of measuring the complex-valued space time channel data accurately and the multipath components are resolved both in space and time domain with 1 GHz measurement bandwidth. Throughout the measurements the line-of-sight (LOS) path is ensured. The parameter estimation is performed using Space-Alternating Generalized Expectation (SAGE) algorithm. Parameters for the directional channel model such as Root Mean Square (RMS) delay spread, Ricean K-factor and angular spread are calculated. Statistical models for the power delay spectrum (PDP) and the power azimuth spectrum (PAP) are given.
