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.

First claim

The invention claimed is:

1. A method for operating a radio communication system which uses Orthogonal Frequency Division Multiplexing (OFDM), comprising:
modulating a first symbol of an OFDM symbol onto a first carrier frequency at a first sending station to produce a first modulated signal;
sending the first modulated signal from the first sending station to a first receiving station via a first transmission channel using an air interface;
changing the first carrier frequenc…
