Adaptive Transmit Power Control As A Mitigating Technique For Rain
Attenuation In Millimeter Wave Wireless Communications In The Tropics.
Millimeter wave (mm-Wave) communication is a promising technology for
high-speed wireless communication like 5G. However, it is highly
susceptible to numerous perturbations that cause significant signal loss
especially rain attenuation. In this paper, we investigate the use of
adaptive transmit power control as a mitigating technique for rain
attenuation in mm-Wave communication. We compare the performance of this
technique to that of adaptive coding and modulation using simulations of
a point-to-point communication link over distances of 10m to 1000m, with
transmit power varying from 100mW to 1W. Virtual experimental results
show that adaptive transmit power control provides better performance
than adap-tive coding and modulation in mitigating rain attenuation in
mm Wave communication, This is promising for 5G technology
implementation and commissioning in the tropics where rainfall is
prevalent all year round.
