Radio communication using OFDMA and IFDMA |
摘要 |
In a method for communicating by radio, a frequency band divided up into a plurality of subcarriers is used for the communication. Messages are sent from a base station to a user station and/or from the user station to the base station. Messages are processed at some times using a first FDMA method such as for example OFDMA and at other times using a second FDMA method such as for example IFDMA. A transmitter and a receiver implement the method.
