Thermal and Intermodulation Noise due to Two-Path Propagation in FM-FDM Systems Using Space Diversity

Space diversity schemes are studied in terms of the relative outage probability for two-path propagation conditior.s. The outage is considered as due to thermal and intermodulation noise in FM-FDM transmission for both selection and combining schemes. The discussion includes common control systems where diversity conditions in several RF channels are controlled by information obtained at a single frequency.
