1、INTERNATIONAL TELECOMMUNICATION UNION)45G134 (b) CCITT Recommendation F.10 concerning character error rate for telegraph communications,unanimously recommendsthat, for the coast-earth station-to-mobile terminal and mobile terminal-to-coast-earth station links, sufficientmargin should be included to
2、overcome adverse propagation conditions. The objective should be that propagationconditions should not contribute any character errors for at least 95% of all calls with mobile terminals within thesatellite service area. With the exception of blockage effects, propagation conditions should not contribute more than8 errors in 100 000 characters with a 99% confidence level for mobile terminals at the edge of the service area.Note - This Recommendation corresponds to CCIR Recommendation 552.
