Abstract
Three imperfections commonly found in transmitter power control (TPC) for direct sequence code division multiple access (DS/CDMA) cellular mobile radios, faulty control of transmission power, unavailable site diversity, and nonuniform user distribution, are investigated. The effects of these TPC imperfections on the traffic capacity of the DS/CDMA mobile communications systems were evaluated through computer simulations. Also, for the TPC system, the accuracy with which the average received signal power must be measured is examined under a wideband signal transmission environment. It is shown that 90% of the traffic capacity with perfect TPC can be achieved by using received signal power measurement whose time interval is larger than eight times the inverse of the maximum Doppler frequency Author(s) Kudoh, E.
