论文摘要
在本文中，我们通过在传输数据包之前传输前序来考虑对多通道Aloha的探索，并证明最大吞吐量可以提高2- exp（-1）= 1.632的系数，可以将其视为探索的增益。在拟议的方法中，基站（BS）需要向活动用户发送反馈信息，以告知多个渠道中传输的前列数的数量，可以可靠地估计为在抗压随机访问中。仿真结果还证实了分析的结果。
In this paper, we consider exploration for multichannel ALOHA by transmitting preambles before transmitting data packets and show that the maximum throughput can be improved by a factor of 2 - exp(-1) = 1.632, which can be seen as the gain of exploration. In the proposed approach, a base station (BS) needs to send the feedback information to active users to inform the numbers of transmitted preambles in multiple channels, which can be reliably estimated as in compressive random access. Simulation results also confirm the results from analysis.
