Abstract: The capacity of
a cellular radio system is largely dependent on its transmitter power control.
Since power control is inherently a real-time problem, to fine the fastest
carrier-to-interference ratio (CIR) balancing algorithm, which forces the
CIR of each cell to converge to a value, has been the essential issue.
An efficient parametric power
control (PPC) scheme is developed in this paper. In this scheme, the power
control is performed at each base by using some parameters provided by
the contral collector, which determines the multiplier of the power update
function, The algebraic property of its CIR balancing algorithm is analyzed.
In an environment with zero noise, the scheme proposes a quick method for
obtaining a least upper bound on the achievable CIR.
The proposed scheme PPC is
also considered in a cellular system with positive receiver noise. The
computational results show that the convergence of the proposed CIR balancing
algorithm is quick and the power consumption is reasonable compared to
distributionschemes. With the proposed algorithm, the CIR's are balanced
sufficiently in a short power control period.
