RADIO COMMUNICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve the frequency diversity effect in a radio communication system which transmits/receives on a plurality of frequencies, using a plurality of slots.

SOLUTION: In a time division multiplex (TDMA-TDD) system of a frequency hopping mode, the apparatus selects a combination of a plurality of frequencies used in the same frame with less correlation with the fading characteristics of a radio propagation line and the spectrum width of other apparatus using the same frequency band. Thus, it obtains a stable frequency diversity effect with a small number of slots against the fading of the radio propagation line and the radio interference with other apparatus using the same frequency band.
