Fast forward link power control in a code division multiple access system

摘要: The radiotelephone demodulates the information received from base station. symbol-energy-to-noise-density (E s /N o ) is estimated over a specified duration. This estimate compared to target E value. updated periodically in order maintain quality of service. If measured greater than target, sends power down command reverse control signaling channel less up station same channel. A multi-carrier transceiver system for code division multiple access includes circuitry up-converting processed user data plurality frequency channels. transceiver, some embodiments, further antennas transmitting each data. method using processing data, and then at different channels, when necessary, through separated space and/or having orthogonal polarization.
