A Novel Architecture for Antenna Arrangement in Wireless Cellular CDMA Systems | | Hamed Saghaei
; | | Date: |
21 Aug 2012 | | Abstract: | Wise arrangement of antennas is critical in wireless cellular systems for
both reduction of co-channel interference (CCI) and increase the quality of
service (QoS). In this paper, a novel architecture for antenna arrangement in
CDMA wireless cellular systems is presented. In this architecture that we
called microzone, every cell is divided into three (or more) zones and
information transmission in downlink channel is done by an antenna which is
placed at the outer region of the related zone. Also, the transmitting signal
by the mobile station (MS) in uplink channel is received by all antennas of the
related cell. Analytical calculations of the received signal to noise ratio
(SIR) and outage probability for both microzone and used architectures show
that proposed architecture has better performance in compared with the used
architecture. Also, simulation results confirm lower outage probability in
uplink channel for microzone architecture. | | Source: | arXiv, 1208.4392 | | Services: | Forum | Review | PDF | Favorites | |
