Performance Analysis of MIMO-HARQ Schemes in LTP for Space Information Networks
Recently, with the development of Ka/Q/V mmWave band high throughput satellites (HTS) and space information networks (SIN), distributed/virtual multiple-input multiple-output (MIMO) over satellite have attracted considerable research interest. In this paper, we propose a novel performance analysis framework for MIMO with orthogonal space-time block coding (OSTBC) under Licklider transmission protocol (LTP) in upcoming SINs, that the closed-form expressions of the mean number of transmission rounds for reliable data delivery in automatic repeat request (ARQ) and hybrid-ARQ (HARQ) schemes is derived by using Laplace transform. Furthermore, we derive throughput expressions for lossless- and truncated-HARQ schemes, and investigate the data delivery delay in LTP over Rayleigh and Rician fading channels. We also verify the accuracy of our derived closed-form expressions of mean number of transmission rounds through the Monte Carlo simulations.
