マルチホップ無線通信システム
Document Type and Number:
Japanese Patent JP5358807
Kind Code:
B2
Abstract:
The present invention provides multi-hop wireless communication systems that easily realize a highly-efficient and highly reliable bi-directional wireless relay transmission by using MIMO network coding. A multi-hop wireless communication system with multiple node devices having a relay function in which each node device is equipped with multiple MIMO antennas and a wireless communication system is constructed by setting up wireless links between the node devices, the multi-hop wireless communication system characterized in that a multiple input multiple output (MIMO) scheme is applied to a transmission/reception scheme of network coding and a space time block coding (STBC) scheme is further applied, concretely, by combining STBC broadcast and MIMO multiple access into network coding, a bi-directional wireless relay transmission that multiplexes a forward link and a backward link in all wireless links is easily realized, each node device performs transmission/reception processing and the relay transmission of data.
