ADAPTIVE DIVERSITY TECHNIQUE FOR MULTIPLE-RELAY-BASED COOPERATIVE WIRELESS COMMUNICATIONS SYSTEM AND EQUIPMENT SUPPORTING THE TECHNIQUE

摘要

PURPOSE: An adaptive diversity technique in a multiple relay based cooperative wireless communication system and an apparatus for supporting the technique are provided to improve performance deterioration of an MRC due to error propagation. CONSTITUTION: N(N=M) diversity paths are selected among M diversity paths(S11). MRC(Maximum Ratio Combining) is performed through the selected N diversity paths(S12). It is determined whether an error is detected about a signal generated after the MRC(S13). When the error is not detected, a signal obtained by performing the MRC through the N diversity paths is decoded(S15). When the error is detected, the M diversity paths are all included to perform MRC(S14).
