Abstract:

Wireless technology has witnessed a
massive amount of attention in communication
domain, not only in industrial field, but in
academia field as well. Multiple-input multipleoutput (MIMO) systems among them has
emerged itself as a promising future technology.
Few of the properties of MIMO include diversity,
spatial multiplexing, and beamforming.
Exploiting these properties can lead us to
improve the data rate. Among these properties
lies polarization diversity which has large
potential to improve the performance in wireless
technologies. This paper contributes in
investigating and implementing interferenceawareness to multiple users with the help of dual
polarized MIMO schemes at ±45º. Various
factors such as Cross-polarization
Discrimination (XPD), Signal to Interference
noise ratio or SINR have been viewed that
utilizes multi-polarization superposition
beamforming (MPS-Beamforming) to optimize
the system design. Simulation results are
provided which shows improvement of the
performance in terms of the Symbol Error Rate
(SER) for the users. The polarization diversity
with beamforming has high potential for the next
generation wireless technologies.
