Teletraffic Analysis of SDMA-Systems with Inhomogeneous MS Location Distribution and Mobility

摘要: One of the most widely used buzzwords in mobile communications recent years is Space Division Multiple Access (SDMA). The introduction an additional space domain multiple access component likely to boost system capacity, due spatial reuse physical channels within one cell. While early approaches SDMA modelling show capacity be gained order 300 400%, there remains some more depth analysis done, as inhomogeneities user distribution are expected cause dramatic drops by SDMA. terminals directly influences number multiplexing. Therefore, it not until detailed models for distribution, mobility and traffic load generated users combined with a model radio subsystem, that realistic approximations these gains possible. In this paper, we discuss issues simulation systems. We present approach integrated modelling, analytic teletraffic dimensioning methods macro- microcellular environments their relevance systems, results.
