Abstract:

Tag-to-tag backscattering is emerging as a promising technology to realise cooperative symbiotic radio communications. This paper aims to maximise the system throughput and backscattering range for multiple and single antenna readers. Specifically, we consider optimal transceiver designs for the multiantenna reader and inter-node location between the tags to maximise the sum of tag-to-tag (T2T) and monostatic backscattering throughput. Whereas, for the single-antenna scenario, we obtain the quality-of-service-aware maximum backscattering range that satisfies the minimum throughput requirements for T2T and tag-to-reader communications. For both scenarios, we have proved the global optimality of the underlying proposed numerical solutions. Apart from numerical solutions, we also proposed low complexity semi-closed-form solutions for sum throughput maximisation in multiantenna reader case and analytical approximations for range maximisation in single antenna case. Finally, simulations validate the proposed solution’s effectiveness and provide nontrivial design insights while demonstrating around 90% improvement over the benchmark.
