Research on technique of cooperative diversity based on two-hop of space-time block coding decode and forward

摘要

According to the fact that encoded cooperative diversity has a better bit error rate than amplify and forward cooperative diversity and multi-hop communication system of wireless sensor network can increase the transmission distance, this paper proposes a new scheme of cooperative diversity based on two-hop of space-time block coding decode and forward, designs a network protocol for this scheme, discusses cooperative synchronization and partner selection, and then simulates the performance of this cooperative method which validates the availability of the proposed scheme.
