Abstract :
A packet switched time-division duplex direct-sequence spread-spectrum (DS-SS) communication system is proposed for operation in mobile and wireless indoor CDMA communications with Rayleigh fading characteristics. A power control method is then proposed for this system capable of providing effective estimates of the fading state of the channel and using this information to adaptively control the uplink transmission power for equalized received power at the base station. The performance of this power control scheme is evaluated by examining the distribution of the received power compared to a reference level for typical indoor communication system parameters
