摘要
本文利用概率密度函数(PDF)方法，建立了多天线融合中心能量探测器平均探测概率的封闭解析表达式。我们考虑了一种i / d ν - μ衰落信道，用于提供集中式协同mimo -认知无线电(CR)网络的详细信息。每个辅助用户(SU)和FC都配有多天线进行报告。FC采用最大比组合(MRC)技术对接收到的信号进行组合，并进行能量检测进行决策。所得到的解析表达式可以作为报告信道的例外实例用于不同的衰落模型。此外，对多天线情况进行了推广。在不同的多天线场景下，对不同的ν - μ值的分析结果证实了所得表达式的正确性。
A PDF based approach for average detection probability of energy detector over ν — μ faded cooperative-MIMO reporting channel
In this paper, we originated a closed form analytical expression for the average detection probability of the energy detector at the fusion centre (FC) with multiple antenna utilizing probability density function (PDF) approach. We consider an i.i.d ν — μ fading channel for providing details regarding the centralized cooperative MIMO-cognitive radio (CR) network. Every secondary users (SU) and FC furnished with multiple antenna for reporting. Using maximal ratio combining (MRC) technique FC combines the received signal and performs energy detection to make a decision. The obtained analytical expression can be utilized for the distinctive fading models as an exceptional instances of reporting channel. Additionally, it is generalized for multiple antenna situation. The arrived expression is Substantiated by analytical results over various ν — μ values with different multiple antenna scenario.
