ABSTRACT:
A subscriber unit for controlling transmission power during the establishment of a communication channel utilizes the transmission of a short code during initial power ramp-up. The short code is a sequence which has a much shorter period than a conventional access code. The ramp-up starts from an initial power level which is quickly increased, while repeatedly transmitting the short code until a detection signal is received by the base station. The use of short codes limits power overshoot and interference.
