空天论坛(2019):单载波线性调制信号在平坦衰落信道上的BMC

文章来源:研究生科           添加时间:2019/9/23 9:09:11

     本次空天论坛邀请Indian Institute of Technology PatnaSudhan Majhi副教授,与我校师生共同探讨单载波线性调制信号在平坦衰落信道上的BMC。具体安排如下,欢迎感兴趣的师生参加。

   一、主 题:The BMC for linearly modulated signals of single-carrier systems over a flat fading channel

   二、主讲人:新加坡南洋理工大学  Sudhan Majhi副教授

   三、时 间:2019925日(周三)9:00-11:00

   四、地 点:清水河校区研究院大楼202

   五、主持人:航空航天学院 阎啸 副教授

   六、内容简介:

        Dr. Sudhan Majhi will introduce his research on the BMC for linearly modulated signals of single-carrier systems over a flat fading channel. A six-class of modulation classification problem including binary phase-shift keying (BPSK), quadrature PSK (QPSK), offset-QPSK (OQPSK), pi/4-QPSK, minimum shift keying (MSK), and 16-quadrature amplitude modulation (16-QAM) will be presented. The proposed BMC method is based on the combination of cumulant and cyclic cumulant. The cumulant is used to decide whether the constellations are from real, circular or rectangular class, which is referred to as macro classifier. The cyclic cumulant is used to classify modulation within a subclass, which is referred to as micro classifier.  In the second problem, a tree-based BMC algorithm for multiple-input multiple-output (MIMO) systems over frequency-selective fading channels will be presented which classifies many of the linearly modulated signals, such as BPSK, QPSK, OQPSK, pi/4-QPSK, 8-PSK, MSK, and 16-QAM modulation formats. Classification is performed by utilizing the combined properties of the correlation functions, cyclic cumulant, and cumulant. In the last, a BMC algorithm for linearly modulated signals of OFDM systems will be presented. The performance of the proposed BMC algorithms are analyzed and compared with existing methods via Monte Carlo simulations. Finally, all the work are validated by providing an experimental setup on NI hardware for an indoor propagation environment.
