Abstract
Satellite and high altitude platforms (HAPs) are an important concept for next generation fixed and mobile communications. To predict indoor field strength levels from such distant transmitters, modifications to the standard indoor ray-tracing concept are proposed. These modifications require an array of virtual transmitters to be placed around the building under test. A range of diversity generation and combining techniques are considered to improve the performance of a 17 GHz indoor to indoor system. Diversity gains are computed and typical generation and combining strategies compared and ranked based on cost, complexity and performance. Investigation of a HAP to indoor environment shows the weakness of illumination from directly overhead
