SYSTEM WITH MULTI-TX/SINGLE-RX STRUCTURE OF CLOSED LOOP-JOINT ORTHOGONAL SPACE-TIME BLOCK CODE

摘要

PURPOSE: A system having a multi output/single input structure of a closed loop-combining orthogonal time space block code is provided to improve diversity performance by having an additional array gain to a fourth diversity gain by having additional array gain. CONSTITUTION: A transmitting terminal(100) combines input bit strings with CSI(Channel State Information) of one bit. The transmitting terminal produces a combination OSTBC(Orthogonal Space-Time Block Coding). The transmitting terminal outputs the block code through the transmitting antennas. The symbol has the same symbol interval. A receiving terminal(200) receives the outputted combination orthogonal space-time block code through a receiving antenna(20).
