Space-time coded cooperation method and system of decresing dependance on inter-channel between nodes

摘要

PURPOSE: An encoding collaborative communication method reducing dependability about an inter-node interchannel between nodes and a system thereof are provided to receive a complete code in a target node in case a partner fails in decryption. CONSTITUTION: The first node(100) transmits the first code encoding the first data to a target node(300) and the second node(200). The first node transmits a time-space block code to the target node. The second node generates the time-space block code by using an Alamouti's scheme about the first code. The target node acquires the first data by using each the time-space block code of the first code and second code.
