Patent ID: 7532659

Claim:
A weighted open loop power control transmitter for controlling transmission power levels using a spread spectrum time division duplex (TDD) technique having frames with timeslots for communication, the transmitter comprising: a demodulator configured to receive the transmitted modulated communication burst and generate a baseband signal; a channel estimation device configured to receive the baseband signal and extract channel information from the baseband signal; a data estimation device configured to interpret the power level of the communication burst; a weighted open loop power controller, the weighted open loop power controller comprising: a power measurement device configured to receive the extracted channel information from the channel estimation device, a pathloss estimation device configured to receive the interpreted power level from the data estimation device and estimate the pathloss (L) and update a long term average of the pathloss (L 0 ) between a receiver and the transmitter, a quality measurement device configured to determine the quality of the estimated pathloss and weight the estimated pathloss by a weighting factor (α), and a transmit power calculation device, wherein the transmit power calculation device is configured to determine the transmitter's power level and to control the receiver's amplifier.
