Analysis and Simulation of Adjacent Service Interference to Vehicle-Equipped Satellite Digital Radio Receivers From Cellular Mobile Terminals

This paper provides detailed analysis and simulation for explol'ing the impact of out-of-band emissions (OOBE) of adjacent wireless services to the Sirius XM digital satellite radio service. Based on an extensive analysis of interference from vehicles with mobile cellular users in realistic roadway conditions, we propose proper methods for determining out of band emission spectral masks that should be used by new WCS cellular subscriber transmitters. in the 2.3 GHz band. Analysis for roadway and propagation conditions in various US cities resulted in the suggested masks. This work presents the first simulation of its ldnd and offers approaches that federal regulators may use to determine spectral masks that allow harmonious co-existence of existing mobile radio listeners with new cellular and fixed broadband mobile services in adjacent spectrum bands.
