[EN] A power estimator 107 controls the voltage supply 108 for an RF power amplifier 105 so that the supply voltage is just sufficient for the amplifier 105 to remain in or near its linear region throughout a burst, slot, or symbol. The power estimator 107 receives information from the scheduler 102 related to the required transmitter power, for example the number of subcarriers in a forthcoming OFDM burst, and refers to a look-up-table 109 to obtain a suitable supply voltage value for the adjustable power supply 108. The power estimator 107 updates the amplifier supply voltage at the symbol rate, which is much lower than the signal sampling rate. The reduction in power consumption is not as great as in a fully envelope-tracking arrangement, but a complicated linearization circuit is not needed and a rapidly-responding voltage supply 108 is not required. The power estimator may respond to the modulation scheme, the coding scheme, the time of transmission, or an average transmit power level. The amplifier may be used in a base station or an access point |
