A COOPERATIVE COMMUNICATION METHOD USING CROSS-LAYER CODING BASE ON HYBRID-ARQ

摘要

PURPOSE: A method is provided to remarkably improve communication performance in a poor wireless channel environment by resolving size and cost of a MIMO system. CONSTITUTION: A method selects a hybrid-ARQ type using a cross-layer coding technique based on importance of a channel environment, BER and throughput when transmitting data in collaboration with a base station(BS), a relay station(RS) and a destination station(DS). At this time, the method includes a stage of judging availability of the channel environment based on effect of Rayleigh fading independently varying with a symbol period and path loss according to a distance.
