Reverse link performance analysis of a cellular CDMA network with fixed overlapping sectors in non-uniform angular traffic
Alagan Anpalagan, Elvino Silveira Sousa · 2002
We study the reverse link performance of a cellular CDMA network that employs fixed overlapping sector antenna architecture (FOSAA) in a hot-spot environment. Simulation results demonstrate the flexibility and effectiveness of the FOSAA in non-uniform angular traffic. The CDF statistics of received SIR are presented for different congestion levels in hot-spot sectors. A scheme with FOSAA can yield on the average 0.8 dB SIR increase over a scheme without FOSAA, when 60% of the mobiles is concentrated in a hot-spot sector in a conventional 3-sector cell. The performance measures such as the mobile transmit power and the antenna selection and sector coverage are also studied.
