Abstract :
A new technique based on vector quantization (VQ) is proposed for interfacing the link-level and the system level analysis of frequency hopping (FH) mobile systems. The method represents an original solution to overcome the problem that the time scales adopted within the two analysis levels are usually different, thus discouraging a direct link between them. The VQ technique is applied, as a test case, to the study of a typical FH-GSM mobile environment. The corresponding results show excellent correlation with those achievable by means of a much more time consuming, as well as often infeasible, direct approach.
