Abstract

Recently, distributed/virtual multiple-input multiple-output (MIMO) technology over satellites have attracted considerable research interest due to the development of Ka-band high throughput satellites (HTS) and space information networks (SINs). In this paper, a novel performance analysis framework is proposed for MIMO with orthogonal space-time block coding (OSTBC) under Licklider transmission protocol (LTP) for emerging SINs, where we derive the closed-form expressions of the mean number of transmission rounds by using Laplace transform for reliable data delivery in automatic repeat request (ARQ) and hybrid-ARQ (HARQ) schemes. Furthermore, we derive the throughput expressions for lossless-and truncated-(H)ARQ schemes, and obtain the maximum throughput value on information rate. We also investigate the file delivery time in LTP over Rayleigh and Rician fading channels. Simulations results are provided to demonstrate the validity of our theoretical results, and show the effect of antenna number on the system performance.

捷联惯导系统OSTBC-MIMO中LTP-HARQ传输方案的设计与分析

近年来，由于ka波段高通量卫星(HTS)和空间信息网络(SINs)的发展，卫星上分布式/虚拟多输入多输出(MIMO)技术引起了广泛的研究兴趣。本文提出了一种新的基于Licklider传输协议(LTP)的正交空时分组编码(OSTBC) MIMO性能分析框架，利用拉普拉斯变换导出了自动重复请求(ARQ)和混合ARQ (HARQ)方案中可靠数据传输的平均传输轮数的封闭表达式。在此基础上，导出了无损-截断-(H)ARQ方案的吞吐量表达式，得到了信息速率下的最大吞吐量值。我们还研究了在瑞利和瑞利衰落信道上LTP的文件传输时间。仿真结果验证了理论结果的有效性，并展示了天线数量对系统性能的影响。
