Problems solved by technology

[0002] In the uplink multiple access relay network, when the user is outside the coverage of the base station, the user transmits information to the base station firstly to the relay node, and then the relay node forwards the user information to the base station, and the relay node only Can forward a user information, the forwarding efficiency is low, and in the process, the relay node simply stores and forwards the received user information, making the information transmission rate and network throughput of the entire uplink multi-access relay network low

Embodiment

[0033] This example is for 4 users D 1 ,D 2 ,D 3 ,D 4 via relay node R 1 ,R 2 ,R 3 ,R 4 transmit information to base station S, and user D 1 ,D 2 ,D 3 ,D 4 Outside the transmission range of base station S.

[0034] In time slot 1, user D 1 ,D 2 ,D 3 ,D 4 Multiple access to selected specific relay nodes within its transmission range, where user D 1 to relay node R 1 ,R 2 ,R 3 ,R 4 send message symbol x 1 , user D 2 to relay node R 2 ,R 3 ,R 4 send message symbol x 2 , user D 3 to relay node R 3 ,R 4 send message symbol x 3 , user D 4 to relay node R 4 send message symbol x 4 . At this time, the relay node R 1 received by user D 1 The message symbol x sent 1 , the relay node R 2 received by user D 1 ,D 2 The message symbol x sent 1 , x 2 , the relay node R 3 received by user D 1 ,D 2 ,D 3 The message symbol x sent 1 , x 2 , x 3 , the relay node R 4 received by user D 1 ,D 2 ,D 3 ,D 4 The message symbol x sent 1 , x 2 , x 3 ,...

Abstract

The invention discloses an information transmission method based on convolutional encoding in an uplink multi-address relay network, which comprises steps as follows: Time Slot 1: every user transmits an information symbol to a specific relay node selected within the respective transmission range; and Time Slot 2: the relay node carries out linear network encoding on the detected user informationsymbol to obtain an encoded signal, gets access into a base station, and meanwhile, transmits the encoded signal to the base station, the base station receives the encoded signal of the relay node, and can decode the user information symbol by simple Viterbi decoding, thereby greatly simplifying the decoding operation of the base station. Compared with the existing information transmission schemein the uplink multi-address relay network, the method disclosed by the invention increases the information transmission rate of the uplink multi-address relay network, and further lowers the decodingcomplexity and time cost of the base station, so that the base station can quickly and reliably decode the user information.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an information transmission method based on convolutional coding in an uplink multiple access relay network, which is suitable for high-speed data transmission in an advanced international mobile communication IMT-Advanced wireless relay network. Background technique [0002] In the uplink multiple access relay network, when the user is outside the coverage of the base station, the user transmits information to the base station firstly to the relay node, and then the relay node forwards the user information to the base station, and the relay node only Can forward a user information, the forwarding efficiency is low, and in the process, the relay node simply stores and forwards the received user information, making the information transmission rate and network throughput of the entire uplink multi-access relay network low .
