Abstract
A method for operating a radio communication system involves the use of OFDM and involves a first sending station modulating a first OFDM symbol onto a first carrier frequency and sending the first OFDM symbol to a first receiving station via a first transmission channel using an air interface. The first sending station changes the first carrier frequency during a time used for sending the first OFDM symbol, the change in the first carrier frequency being made independently of a change in transmission characteristics of the first transmission channel over time. A fast frequency hopping system is disclosed.
