METHOD AND APPARATUS FOR RECEIVING AND TRANSMITTING USING MIMO MULTIPLE HYBRID ARQ SCHEME BASED ON SPACE-TIME BLOCK CODE

摘要

PURPOSE: An apparatus for receiving and transmitting using MIMO multiple hybrid ARQ scheme based on STBC(Space-Time Block Code) and a method thereof provided to solve a matching problem between initial transmitted symbols and retransmitted symbols.;CONSTITUTION: Symbols are included in a plurality of sub packets. The symbols creates an initial transmission matrix by diagonal interleaving in a time domain and a space domain(110). The symbol of a sub packet copes with the success of the transmission in the initial transmission matrix. A retransmission matrix is created by substituting the symbols of sub-packet into the sub packet symbols corresponding to the transmission failure(130). One or more space-time blocks are retransmitted through a plurality of antennas(140).;COPYRIGHT KIPO 2012
