Channel Characterization and Validation of Ray Tracing Simulations with Measurements at 60 GHz in Office Environment

Résumé

The main target of this paper is to compare and validate the simulation results acquired from the in-house developed Ray Tracing (RT) tool with the measurements conducted in a typical office environment at 60 GHz. The in-house built RT tool utilizes the Image Theory (IT) for finding the propagation paths between the Transmitter (Tx) and the Receiver (Rx). The channel characteristics considered for the analysis are the path loss (PL), Power Angular Spectrum (PAS) and Root Mean Square (RMS) Delay Spread (DS). The target is to consider the match between the measurement and simulation results, and determine the effectiveness of simulations in predicting different characteristics of the channel at 60 GHz in an office environment. The indoor channel is analyzed at nine different locations, where we have studied the channel characteristics with respect to two receiver antenna orientations i.e., Direct Orientation (DO) and the Best Indirect Orientation (BIO). The observed RMS error between measured and simulated path loss is around 2.8 dB and 1.8 dB in DO and BIO, respectively. Measurement and simulation results can be used in e.g. physical layer performance studies that exploit the multipath propagation in an indoor office environment. Simulation results show that the proposed RT tool can be useful and reliable for characterizing the 60 GHz indoor channel.
