| Abstract | In this paper, a method of Gaussian approximation (GA) in a formulated manner is proposed to model inter-cell interference for OFDMA systems with beamforming. It is based on the parameters of 3GPP spatial channel model (SCM). For single-antenna OFDMA systems, the WINNER project proposed that the inter-cell interference can be modeled as white Gaussian noise. However, as indicated by itself, the validity of GA is not guaranteed for the scenarios with dominant interferer and multi-antenna. In this paper, the GA methodis extended into multi- antenna OFDMA systems with beamforming and the scenario with dominant interferer as well. A formula is proposed to calculate the variance of modeled Gaussian noise directly with the SCM parameters of AoD, AoA and power of each path. With this method, the complicated spatial channel models in interfering cells are not required for some applications, which help to speed up the simulation process with much lower computation and memory requirements. |

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.
