ABSTRACT:
Cooperative relaying for a system that consists of different
configurations of a collocated and uniform linear antenna is analyzed. The amplify-and-forward
relaying (AF) and selection combining (S-AF) schemes based on maximal ratio
combining (MRC) method for single- and multi-relay are investigated. In this
study, the bit-error-rate (BER) expression for collocated and uniform linear
antenna in cooperative communication system over flat Rayleigh fading channel
is derived. The result for 3-element collocated antennas (tripole) shows
improvement in performance over dual-polarized antennas. Also increasing number
of tripole antenna does not add improvement.
