Abstract

The use of Q/V band feeder links and Ka band user links is a feasible solution to support the next iteration of High Throughput Satellite. The gateway transmit diversity technique is a way to compensate the rain attenuation of Q/V band feeder links. This paper analyzes a practical combination scheme that combinates N-active (K=2) with N+1 diversity method in detail from the working principle, gateway handover status transfer process, evaluation of system availability and implementation complexity. Compared with the existing N+P scheme, the proposed scheme can provide higher system availability and more stable user experience under the condition of properly increasing the complexity of payload design. Compared with N-active scheme that has been reported, it is much easier to implement in engineering and more cost-effective. As a result, the combination scheme is an optimized solution based on a tradeoff between performance improvement and complexity of the payload.
