METHOD FOR COOPERATIVE TRANSMISSION OF SPACE-TIME CYCLIC DELAY DIVERSITY WITH ADAPTIVE SELECTION

摘要

PURPOSE: A method for cooperative transmission of space-time cyclic delay diversity with an adaptive selection is provided to transmit data without any burden to an additional receiver in a situation where the number of repeaters is not regular. CONSTITUTION: At least three repeaters are divided into a first group and a second group(S210). If the number of repeaters is an even number, the repeaters are equally divided. If the number of repeaters is an odd number, the repeaters which belong to the second group are one larger than the first group. The repeaters of the first and second groups perform orthogonal space-time block coding for the received data(S220), and delays the circulation of the result codes of the orthogonal time-spatial block coding(S230).
