Reduced Complexity MIMO Concatenated Code in Fading Channels
收藏 引用
IEEE COMMUNICATIONS LETTERS 2011年 第7期15卷 746-748页
作者: An, Wei Ning Hamouda, Walaa Concordia Univ Dept Elect & Comp Engn Montreal PQ H3G 1M8 Canada
In conventional concatenations of Convolutional Codes (CC) and Space-Time Block Codes (STBC), the CC and STBC are utilized to provide coding gain and spatial diversity, respectively. We propose a concatenated code tha... 详细信息

Self-Interference-Threshold-Based MIMO Full-Duplex Precoding
收藏 引用
IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY 2015年 第8期64卷 3803-3807页
作者: Huberman, Sean Tho Le-Ngoc McGill Univ Dept Elect & Comp Engn Montreal PQ H3A 0E9 Canada
The full-duplex (FD) single-user multiple-input-multiple-output (SU-MIMO) sum-rate maximization problem leads to a nonconvex optimization problem. In this paper, we introduce a maximum self-interference threshold (SIT... 详细信息
