| Abstract | For a multiple input multiple output (MIMO) broadcast channel, the receiver-side cooperation could make the system less dependent on the channel state information at the transmitter (CSIT), and thus it is of great significance for practical applications, where the CSIT is usually difficult to perfectly obtain. In order to provide a theoretical guide for the implementation of MIMO broadcast system with receiver cooperation, this paper focuses on the power allocation problem. In the problem, the transmission power is allocated between the transmission downlink and cooperation links among receivers, under the total power constraint. Particularly, the compress-and-forward cooperation strategy is employed. By recasting the problem as a polynomial rooting problem, we finally propose a nearly optimal power allocation strategy. Simulation results show that this strategy leads to negligible loss compared to the exhaustive search method. |

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.
