SPACE TIME CODING METHOD IN ORTHOGONAL NETWORK AND RELAY TRANSMISSION SYSTEM

摘要

A space time coding method in orthogonal network and a relay transmission system are provided. The method is used in the wireless communication network including a destination node, a source node and a relay node, which includes: step A, the source node broadcasts a data information to the relay node and the destination node, the step needs TSR pieces of symbol periods; step B, the relay node makes orthogonal network space time coding after the data information transmitted from the source node is received, and transmits the coded data to the destination node, the step needs 2 symbol periods. The present invention solves the technical problems that the network throughput of the relay node network is lower, and diversity loss is bigger in the wireless communication network including a destination node, a source node and a relay node.
