Abstract :
This paper introduces the use of dual circular polarisation multiplexing (DCPM) for land mobile satellite communication (LMS) systems as a simpler alternative to MIMO. The conditions for switching from traditional polarisation-separated MIMO to DCPM are analysed using synthetic data and data obtained from a previous LMS measurement campaign. Metrics used for performance comparison include the channel ergodic capacity, channel correlation, and the channel cross-polar ratio (XPR). DCPM brings with it the benefits of simpler receiver based processing dependent only upon the mobile.
