MULTI-SOURCE COOPERATIVE METHOD AND MULTI-SOURCE COOPERATIVE SYSTEM USING OPPORTUNISTIC SOURCE SELECTION

摘要

PURPOSE: A multi-source cooperative method and a multi-source cooperative system using opportunistic source selection method are provided to simultaneously obtain space diversity and time diversity gain using queue of each terminal. CONSTITUTION: A control unit divides each time slot into a plurality of sub time slots(S1). A terminal transmits signal which is capable of being received to each terminal(S2). The control unit determines optimal terminal in the corresponding sub time slot(S6). A distributed timer is completed earlier than other timers in the optimal terminal. The optimal terminal transmits a data block to a receiver(S7).
