摘要/Abstract

摘要：

在碰撞约束和非理想信道信息下，研究认知多址接入信道中多个次用户接入主用户频谱的有效吞吐量问题。在机会频谱接入方式（OSA）下，定义有效吞吐量并作为次用户的性能指标。考虑信道质量信息，在信道质量分布参数未知的情况下采用有限的信道样本对参数进行估计，并对非理想感知下次用户的性能进行分析。通过仿真实验，分别讨论了信道质量门限与碰撞概率及次用户性能之间的关系，对比了理想感知和非理想感知下次用户的性能，并与其他算法进行对比，验证了本文接入策略的有效性。

Abstract:

The problem of effective throughput of multiple secondary users access to the spectrum of primary user in the cognitive multiple access channel under collision constraints and imperfect channel state information was discussed. Effective throughput was defined and used as the performance metric for secondary users under opportunity spectrum access（OSA）. The channel quality information was considered and limited number of channel samples were used to estimate the parameter of unknown channel quality distribution and the performance of secondary users under imperfect sensing was analyzed. The performance of secondary users under perfect sensing and imperfect sensing was compared by simulations. Moreover, the validity of proposed access strategy was verified by comparing it with other algorithm.

Key words: cognitive radio, multiple access, effective throughput, imperfect channel, channel quality
