Abstract

Relay transmission technology is the key technology for communication in the decentralized wireless network In multi-hop relay transmissions, employing digital fountain code can greatly reduce the transmission of feedback information, improve the transmission efficiency of the network, and decrease the transmission time. In this paper, a relay pairs transmission scheme based on fountain code transmission is proposed. Via relay pairs cooperation and rotated constellation technology, signal space diversity is obtained without reducing the bandwidth efficiency and the transmission performance of the relay chain is improved. Simulations show that the performance of the multi-hop relay pairs transmission scheme based on digital fountain code is further upgraded besides achieving packet diversity and signal space diversity. Meanwhile, packet transmission number and transmission time are both reduced.
