CELLULAR SYSTEM CAPACITY and PERFORMANCE IMPROVEMENT with SDMA
نویسندگان
چکیده
The need to find solutions that would support the increasing number of users has been stimulating many research groups to explore new techniques to increase the system capacity of the mobile communication systems. In this paper, the impact of SDMA (Space Division Multiple Access) technique in system performance and capacity is evaluated. Carrier-to Interference (C/I) level for FDMA / TDMA and for CDMA based type systems is analyzed. Spectrum efficiency improvement and its impact on system capacity (maximum users per cell) due to SDMA is also shown in simulation results.
