Abstract: A method and apparatus for the control of each mobile station within a Code Division Multiple Access (CDMA) communications network using simple pilot tones generated and controlled by a base station is described that is intended for use with full duplex, point to multipoint communications networks, particularly low mobility, cellular configurations. A pilot tone signal is added to a voice channel transmitted from a base station to a mobile station. The voice and pilot tone signals are further modulated using direct sequence spread spectrum (DSSS) techniques. The pilot tone serves several purposes. It allows the receive hardware to recover a frequency reference based on the DSSS code rate, which is used to synthesize the receiver tuning, generate the DSSS decoding sequence and synchronously demodulate the voice channel at the mobile station. The amplitude of the forward channel pilot tone is used to control the return channel transmit level. The invention implements a combined open and closed loop mechanism.
