FIELD: radio engineering, communication.
SUBSTANCE: present invention relates to a method for network orthogonal space-time coding and a relay transmission system. The method is used in a wireless communication network, having a target node, a source node and a relay node, and includes: step A where the source node broadcasts information in data form to the relay node and the target node, wherein TSR symbol periods are required for step A, and step B, where after receiving information in data form, transmitted by the source node, the relay node performs network orthogonal space-time coding and transmits the coded data to the target node, wherein two symbol periods are required for step B.
EFFECT: high network throughput, fewer data packet transmissions, improved fault-tolerance during diversity reception in a wireless communication network having a target node, a source node and a relay node.
