摘要

在本文中，我们计算了混合ARQ方案在有槽准静态多天线信道上的吞吐量。具体来说，我们考虑了开槽Aloha，混合ARQ Chase合并(HARQ-CC)和混合ARQ增量冗余(HARQ-IR)方案。利用奖励更新定理，我们采用[1]中多天线信道的封闭式吞吐量方程。此外，我们研究了天线数量对这些HARQ方案吞吐量的影响，涉及提供的负载和目标速率。

Performance of Hybrid ARQ in Block Fading Multiantenna Channels

In this paper, we compute the throughput of Hybrid ARQ schemes over slotted quasi static multiantenna channels. Specifically, we consider slotted Aloha, Hybrid ARQ Chase combining (HARQ-CC), and Hybrid ARQ incremental redundancy (HARQ-IR) schemes. Using reward-renewal theorem, we adopt closed-form throughput equations in [1] for multiantenna channels. Moreover, we investigate the affect of number of antennas on the throughput of these HARQ schemes with respect to offered load and target rate.
