A New Multiple Gateway Transmit Diversity Technique for Future Satellite Networks
文献摘要：
The next generation of High Throughput Satellite(HTS)will exploit Q/V band for the feeder link and Ka band for the user link.The exploita-tion of multiple gateways(GWs)is a transmit diver-sity measure to compensate severe rain attenuation of Q/V band feeder links.This paper introduces a new smart gateway diversity combination scheme that combinates N-active(K=2)and N+1 diversity method in detail from the working principle,gateway switching strategy,evaluation of system availability and implementation complexity.In addition,a feeder link outage event prediction algorithm featuring com-bination scheme is given detailly based on modified time-adaptive linear regression.Compared with the existing N+P scheme,the proposed scheme can pro-vide higher system availability and more stable user's 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 a realistic so-lution based on a trade-off between performance im-provement and implementation complexity.
