Abstract
Owing to the fact that wireless communication
has an edge over its wired counterpart in terms of low cost and ease of
deployment, transmission principles in wireless communications are actually
more complex due to the mobile radio channel that imposed a potentially massive
limitations on the system performance. A mobile communication system employing
code division multiple access (CDMA) also suffers channel impairment due to
interference during propagation that reduced the overall system performance and
therefore system quality of service (QoS). As the system QoS is
interference-limited, a power control problem can be formulated as nonlinear
optimization with a system-wide objective subject to power constraint. This
paper focuses on multi-objective power control based on bacterial foraging
algorithm (BFA) technique to combat adverse effects of excessive time-varying
interferences such as channel fading, multiple access interference, round-trip
delay and noise in a CDMA system. This is aimed at achieving higher
communication link quality, better system capacity, improved battery power and
reduce outage probability under time-varying interference Raleigh fading
channel and Additive white Gaussian noise at the input of the receiver. This
paper also examines the performance of the power control technique for
different mobile velocities at the high interference environment and the outage
performance was found to be very small.
