辅助信息在二级频谱市场中的价值

The value of Side Information in Secondary Spectrum Markets

Arnob Ghosh, Saswati Sarkar, Randall Berry

摘要:

在二级频谱市场中,初级用户为他们未使用的信道向二级用户定价。初选的收益取决于其竞争对手未使用的渠道的可用性。我们认为一个模型是一个主要的可以获得其竞争对手的信道状态信息(C-CSI)的成本。我们制定了一个两个主要之间的游戏,每个主要决定是否收购C-CSI,然后选择其价格的基础上。首先,我们刻画了这个游戏的纳什均衡(NE)的对称模型的C-CSI是完美的。我们发现,一个主要的收益是独立的C-CSI收购成本。然后,我们概括我们的分析,以允许不完美的估计和情况下,两个主有不同的C-CSI成本或不同的信道可用性。有趣的是,我们的研究结果表明,当存在估计误差时,初选的收益会增加。我们还表明,令人惊讶的是,当C-CSI获取成本降低时,初选的预期收益可能会降低初选具有不同的可用性。

英文摘要:

In a secondary spectrum market primaries set prices for their unused channels to the secondaries. The payoff of a primary depends on the availability of unused channels of its competitors. We consider a model were a primary can acquire its competitor's channel state information (C-CSI) at a cost. We formulate a game between two primaries where each primary decides whether to acquire C-CSI or not and then selects its price based on that. We first characterize the Nash Equilibrium (NE) of this game for a symmetric model where the C-CSI is perfect. We show that the payoff of a primary is independent of the C-CSI acquisition cost. We then generalize our analysis to allow for imperfect estimation and cases where the two primaries have different C-CSI costs or different channel availabilities. Our results show interestingly that the payoff of a primary increases when there is estimation error. We also show that surprisingly, the expected payoff of a primary may decrease when the C-CSI acquisition cost decreases when primaries have different availabilities.
