Spatial considerations in the design and simulation of cellular multiple access systems
M.P. Lötter, Pieter van Rooyen · 2002
Some spatial considerations in the design and simulation of cellular communication systems are discussed. In particular, new probability density functions (PDF) are used to describe the location of users in a cellular system and analytical expressions for the PDF of the angle of arrival (AOA) of signals at the subscriber are derived for systems employing directional antennas or smart antennas. These expressions can be used to derive analytic expressions for the bit error rate performance of space division multiple access (SDMA) communication systems.
