ORTHOGONAL FREQUENCY AND CODE HOPPING MULTIPLEXING COMMUNICATIONS METHOD

摘要

The present invention relates to an Orthogonal Frequency and Code Hopping Multiplexing (OFCHM) communication method based Orthogonal Frequency Division Multiplexing (OFDM) in a wireless communication system in which a plurality of communication channels are syn¬ chronized through a single medium. The present invention includes six different types of spreading and hopping methods, a method of controlling spreading and hopping depending on channel states, and a method of de¬ termining whether radio resources, consisting of subcarriers and orthogonal codewords, are allocated in a hopping manner according to the quality of service in the OFCHM communication method based OFDM. Furthermore, the present invention includes an embodiment of employing multiple array antennas. For this purpose, a method of combining a collision comparator and controller for monitoring the operations of a subcarrier group hopping pattern generator and an orthogonal code hopping pattern generator, a multiplexer and data symbol mapper, and the collision of hopping patterns that are composed of subcarriers and orthogonal codewords, and comparing data symbols to be transmitted to second communication stations to determine whether the data symbols collide in a symbol interval, a beam-forming processor for managing the operation of multiple array antennas, and a weighting vector controller is proposed.
