COOPERATIVE COMMUNICATION METHOD FOR TRANSMITTING EACH SIGNAL TO MULTIPLE RECEIVERS USING MULTIPLE RELAYS

摘要

PURPOSE: A cooperative communication method for transmitting each signal to multiple receivers using multiple relays is provided to improve the performance of a cooperative communication system by removing the interference signal of the same channel. CONSTITUTION: A signal source encodes a signal through an orthogonal code. The signal source transmits encoded signal to a plurality of relays(S302). The each relay reproduces the encoded signals and decodes them through the orthogonal code. The delays transmits the signal to a plurality of destinations(S304).
