| Abstract | By considering the large-system regimes, we analyze the asymptotic performance of a multiple-input multiple-output (MIMO) multiple-access (MA) wireless network in the presence of spatial correlation at the transmitters (i.e., mobile stations) and the receiver (i.e., base station) with particular emphasis on the receive antennas utilizing pattern diversity. Using the replica method originally developed in statistical physics, we are able to derive analytical solutions to the spectral efficiency of the MIMO-MA systems for any given arbitrary input signal distributions at the transmitters assuming the information-theoretic optimum decoding at the receivers. Our results are general in that they encompass lots of previously published results for degenerate cases. In addition, based on the asymptotic solution, we propose a computation-efficient algorithm to determine the asymptotic optimum transmit signal covariance matrices that can maximize the spectral efficiency of the MA network when only the slow-varying channel spatial covariance information is available at the transmitters. |

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.
