摘要

研究了不同需求分配策略下突发目标需求分配多址(BTDAMA)方案的相对性能。提出了一种采用混合需求分配策略的卫星多址接入方案(BTDAMA- hd)，该方案将BTDAMA方案的突发目标需求分配策略与可变速率DAMA方案的分组保留需求分配策略相结合。在Pareto ON/OFF流量源下，通过计算机仿真比较了BTDAMA-PD(纯需求分配)和BTDAMA-HD的延迟性能。结果表明，BTDAMA-HD在GEO卫星信道上具有较好的延迟和延迟抖动性能。

Improved Burst Target Demand Assignment Multiple Access (BTDAMA) for GEO Satellite Networks

This paper examines the relative performances of the BTDAMA (Burst Target Demand Assignment Multiple Access) schemes with different demand assignment strategies. A new satellite multiple access scheme employing hybrid demand assignment strategy (BTDAMA-HD) is proposed which combines the burst target demand assignment strategy of the BTDAMA schemes with the packets reserved demand assignment strategy of the variable rate DAMA schemes. The delay performances of BTDAMA-PD (pure demand assignment) and BTDAMA-HD were compared by computer simulation under Pareto ON/OFF traffic source. The results demonstrate that BTDAMA-HD can offer better delay and delay jitter performance over GEO satellite channel.
