초록
In this paper, we propose a robust transmission scheme using Aggregated Physical Protocol Data Units (APPDU). The proposed method includes a Media Access Control (MAC) layer control for determining the number of preambles to be inserted based on the feed-back reply signal from a receiver; the generation of a multi-preamble aggregation frame by inserting the determined number of preambles into frames received from an upper layer; a physical layer for forming the multi-preamble aggregation frame generated in a data processing unit by using a physical layer frame; and the transmission of the formed multi-preamble aggregation frame. The proposed technique obtains performance improvement of about 3 dB in terms of SNR and 35% in terms of throughput efficiency. © 2010 IEEE.
