COOPERATIVE COMMUNICATION SYSTEM USING SIGNAL SPACE DIVERSITY BASED ON ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING AND METHOD THEREOF

摘要

PURPOSE: A cooperative communication system using signal space diversity based on OFDM(Orthogonal Frequency Division Multiplexing) is provided to perform super high speed communication with low power and low costs in an inferior communication system. CONSTITUTION: A first transmission terminal transmits a first signal based on OFDM method to a second transmission terminal and a destination terminal. The first transmission terminal performs a signal space diversity modulation process for the received signal from the second transmission terminal. The first transmission terminal transmits the processed signal to the second transmission terminal and the destination terminal. The first transmission terminal transmits the second signal to the destination terminal.
