1、 北京邮电大学李道本教授学术报告北京邮电大学李道本教授学术报告报告题目：报告题目： Overlapped Multiplexing Principle and its application 时间：时间：6 月 16 日（周四）15:30地点：地点：图书馆报告厅报告内容简介：报告内容简介：Based on the Overlapped Multiplexing Principle revealed by speaker a X frequency F, time T domain OVXDM (Overlapped X Division Multiplexing) Coding scheme

2、is proposed. By the data weighted shift overlapped version of any Multiplexing Transfer or Impulse Response Function with limited duration, the coding gain and spectral efficiency are both achieved. The heavier the overlap of the data weighted, the higher the coding gain and the spectral efficiency

3、(channel capacity) as well as the closer of The OVXDM coding output to the optimum complex Gaussian distribution. One of the bit error probability upper bound is estimated. OVTDM and OVFDM are a pair of dual codes. Both theoretical analysis and testified simulations show that OVFDM and OVTDM are sui

4、table for high spectral efficiency application. Their spectral efficiency (channel capacity) are all nearly linear to SNR rather than the well-know logarithm to SNR. X can be expanded to code C, space S and hybrid H domain etc.报告人简介：报告人简介：北京邮电大学教授，博士生导师，国家有突出贡献专家，享受政府特殊津贴。长期 从事信息论，信道编码，信号检测与估计，移动通信等领域的基础研究与开发工作。先后 领导主持过：四项重点国家自然科学基金，两项国家科技 863，两项国家移动通信重大专 项等课题。拥有 119 项 PCT 国际发明专利，发表专著 8 本，重要文章 200 余篇，其中被 SCI，EI 等数据库收录的有 237 篇。曾担任多届中国电子学会信息论专业委员会委员，中 国通信学会通信理论专业委员会委员，中国航空航天学会信号与信息处理专业委员会委员。注：听报告的学生请携带校园卡记录创新学分
