这个是芬兰人写的《WCDMA无线网络规划与优化》书上对应的Matlab源代码。这本书很经典。

%BESTSERVERULAREA   [NEEDEDMSTXPOWER BESTSERVER DOMINANCE] = BESTSERVERVULAREA(PERF, 
%                   LINKLOSS, MSMAXTXPOW, SPEED, BITRATE, ACTIVESETT)
%                   calculates dominance, best servers and MStxPowers in uplink to each
%                   pixel. Calculation is done by using the coverage threshold found in
%                   rlbul. This is corrected to the wanted bit-rate and MS speed assuming
%                   that perf.covth was for wideAreaCovSpeed and wideAreaCovR.
%				  
%Inputs:
%   PERF            : structure holding the performances of the BSs.
%   LINKLOSS        : (NumBSs * yPixels * xPixels) matrix holding the link loss of BS, 
%                     1...NumBSs, to the map pixels.
%   MSMAXTXPOW      : maximum transmit power of the mobiles (currently all mobiles have
%                     same max. TX power).
%   ACTIVESETT      : (k, j, i), k=1, ..., numBSs, j=1, ..., yPixels, i=1, ..., xPixels, matrix
%                     holding 1 if BS(k) is in the active set in pixel (j, i) and 0 if not.
%                     This is only if perchPowerSwitch == 3. Otherwise an empty matrix.
%	 SPEED:            The MS speed for which the calculations are done.
%	 BITRATE:          Bit-rate (service) that MS is using.
%Outputs:
%   NEEDEDMSTXPOWER : (xPixels x yPixels) matrix holding the minimum needed average 
%                     (over multi-path fading) transmit powers needed in each pixel, 999
%                     if outage.
%   BESTSERVER      : (xPixels x yPixels) matrix where element [i, j] is the best server
%                     at pixel (i, j), 0 if outage.
%   DOMINANCE       : (xPixels x yPixels) matrix where element [i, j] is signal strength
%                     from best server, -999 if outage
%Comment:
%   Best server in this context is that BS to which mobile has to transmit with the
%   smallest power.
