Abstract
One of operational problem in Code Division Multiple Access (CDMA) there is breathing effect. Breathing caused by fully cell, so user at enough long distances haven't connected services therefore pretending the cell to be mise. If the user number less then cell capacity will be previous shape, so user could be connected again therewise the cell capacity growth up. Prepably a few cells in neighbouring regardless then the cell boundary hasn't included (blankspot). On digital communication the connection quality adjustment by parameter comparison of energy per bit per noise gain density was known Eb/No. Seen on Eb/No value depends on user reflection gain which determine by choosen channel model. This paper will be tried for step models; Free Space, Lee, and Hata therefore choose by user itself to be determined the model of fitted on.
