Error Rate of High-Frequency Multichannel Fleet Broadcast System.
Abstract
A data sample of the error-rate performance of the high-frequency multichannel Fleet broadcast system under worst-case conditions was taken in the area of the Caribbean Sea. In an interference-free situation, median bit error rates over a 24-hour period were found to be about 0.01 for single channel, 0.0015 for dual-inband diversity, and about 0.0002 for quad diversity. Operating frequencies too far below the maximum unsable frequency will cause a serious rise in this rate. It was also discovered that since atmospheric noise had a noticeable effect on the error threshold at higher daytime frequencies, higher effective radiated power will improve overall error-rate performance.
