Further investigations into signal level enhancements over two over-sea radio paths

This study focuses on hourly breakdown of received signal strength enhancement events, short-time fading characteristics during and outside enhancement and co-site and co-frequency enhancements on two over-sea, trans-horizon paths. Hourly breakdown of enhancement events reveals a diurnal pattern, with a greater percentage of enhanced signal strengths predominantly occurring during late afternoon/evening periods and the least during morning. Generally, signal strength enhancement tends to reduce the short-time fading. Concurrent as well as isolated signal strength enhancements at both the receiving sites/frequencies have been observed, which can have implications in radio network interference management.
