摘要

考虑星地融合非正交多播和单播传输场景，并构建星地融合网络多组多播和单播下行传输系统模型。为有效提升星地融合网络的频谱效率，提出基于速率分割的非正交传输波束赋形方案，从而建立最大最小公平（MMF）波束赋形设计问题以分别优化基站和卫星的发送波束赋形向量。为解决因变量耦合导致约束非凸的问题，提出一种基于连续凸逼近的算法迭代求解。仿真结果表明，与传统非速率分割方案和层分复用方案相比，所提方案能够显著提升星地融合网络的MMF传输速率。

Abstract

A non-orthogonal multicast and unicast transmission scenarios in the satellite-terrestrial integrated networks (STIN was considered)

and a system model of joint multi-group multicast and unicast downlink transmitting was constructed.In order to improved the spectral effi ciency of STIN

a beamforming scheme that non-orthogonal transmission based on rate splitting was proposed

where a max-min fair (MMF) beamforming design problem was established to optimized transmit beamforming vector of base station and satellite respectively.And then

considered non-convex constraint caused by variable coupling in the problem

an iterative algorithm based on successive convex approximation to solved the optimization problem was proposed.Simulation results showed that our proposed scheme could improved eff ectively the MMF transmitting rate of the STIN in contrast with the traditional non-rate splitting and layer division multiplexing schemes.
