Space time block codes encoding method by using auxiliary symbol

1. Technical Field of the invention defined in the claims The present invention relates to a MIMO (multiple-input multiple-output) communication system using multiple transmission antennas, the space-time block code encoding during transmission rate and transmission introduces the concept of secondary symbols to control the diversity order one space-time block code encoding thing of ways. 2. The invention attempts to solve the technical challenges The present invention rates that while having an increase in the other hand less decoding complexity of the structure of the space-time block code by introducing the concept of the secondary symbols in the space-time block codes to maintain orthogonality to have a higher rate than conventional orthogonal space-time block code encoding method and to provide a space-time block code encoding method having the secondary symbols to control the diversity order that the purpose. 3. Resolution of the subject matter of the invention, The present invention, in the space-time block code encoding method of the MIMO system, comprising: a first process of receiving the binary data for transmission; A second process of determining the symbols and the free auxiliary symbol by dividing the input binary data at a predetermined bit unit; And including a third step of transmitting the encoded symbols and the free auxiliary symbol the generated according to the encoding matrix. 4. An important use of the invention, The invention yiyongdoem like multi-antenna system.
