Analysis and Simulation of Adjacent Service Interference to Vehicle-Equipped Digital Wireless Receivers from Cellular Mobile Terminals

This paper provides detailed analysis and simulation for exploring the impact of out-of-band emissions (OOBE) from adjacent wireless cellular services to receive-only digital mobile radio services. 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 in interference coordination in mobile to mobile interference conditions. Analysis for roadway and propagation conditions in various US cities resulted in the suggested interference protection masks. This work offers approaches that can be used to determine spectral masks to allow harmonious co-existence of mobile digital receivers with new cellular and fixed broadband mobile services that operate in adjacent spectrum bands.
