This code is a simulation of 3 user Distributed Power Control
algorithm used in CDMA networks for interference coordination.

%Variables: SIR-Signal to Interference+Noise Ratio
% H-channel gain matrix; Gamm- Gamm-Required SIR at each receiver
% P-power available at each transmitter, N-noise at each
% receiver
% Err-error.Difference between required SIR and actual SIR. Measure
% of convergence of algorithm

%Algorithm: p(t+1,i)=Gamm(i)/SIR(t,i)*p(t,i) where t-is time index and
%i-user index.
%We perfom this algorithm until we conver to required SIR levels
