calccosited.m

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。

%CALCCOSITED   ISCOSITED = CALCCOSITED(BASESTATION, DELTALOCALLOWED) calculate cells in the
%              basestation structure, which are co-sited. Co-sited cells are cells which are 
%              not more afar each other than DELTALOCALLOWED.
%              If DELTALOCALLOWED is ommitted, the map resolution is taken instead
