Effects of Power Control Error on the System User Capacity of DS/CDMA Cellular Mobile Radios [PDF]

, 1992
User capacity of a DS/CDMA cellular mobile radio system employing transmitter power control (TPC) is investigated. Assuming log-normally distributed control error, outage probability is evaluated through computer simulations.
