Hit statistics in FH-CDMA unslotted packet networks

摘要

This correspondence is concerned with the statistical dependence of hits due to multiple-access interference in the time-unslotted frequency-hopping (FH) packet networks. Relying on the technique of joint probability generating functions (PGFs), we give a formal proof that if the ratio of the number of interfering packets to the number of frequency slots K/q is held constant, hits due to multiple-access interference are asymptotically independent as q/spl rarr//spl infin/. We also derive expressions for the correlation coefficients of hits in the packet.
