| Abstract | In this paper, we investigate the multiple-input multiple-output (MIMO) transceiver design under an interesting power model named mixed power constraints. In the considered power model, several antenna subsets are constrained by sum power constraints while the other antennas are subject to per-antenna power constraints. This kind of transceiver designs includes both the transceiver designs under sum power constraint and per-antenna power constraint as its special cases. This kind of designs is of critical importance for distributed antenna systems (DASs) with heterogeneous remote radio heads (RRHs) such as cloud radio access networks (C-RANs). In our work, we try to solve the optimization problem in an analytical way instead of using some famous software packages e.g., CVX or SeDuMi. In our work, to strike tradeoffs between performance and complexity, both iterative and non-iterative solutions are proposed. Interestingly the non-iterative solution can be interpreted as a matrix-version water-filling solution extended from the well-known and extensively studied vector version. Finally, simulation results demonstrate the accuracy of our theoretical results.本文中, 我们研究了在混合功率约束条件下, 多输入输出系统的收发机的设计问题。我们考虑的功率模型中, 部分天线的发送功率服从和功率约束, 而其他的天线功率约束服从单天线功率约束。这种情况下, 收发机的设计既包括和功率约束条件下的收发机的设计, 又包括单天线约束条件下的收发机的设计。这种设计在异构的分布式天线系统中非常重要, 比如CRAN网络中。在我们的工作中, 我们尝试着以一种解析的方式求解优化问题, 而不是利用一些有名的软件包, 比如CVX或SeDuMi。另外, 为了在性能和复杂度之间寻求一个好的折中, 我们提出了迭代的和非迭代的算法。有趣的是, 非迭代的解可以理解为一种矩阵版的注水解, 这是从著名的矢量版的注水解扩展而来的。最后, 仿真结果说明了理论分析的准确性。 |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
