摘要： The present invention provides a method and system for transmitting a multi-frequency signal composed of discrete tones of constant envelope parts that are amplified by a bank of fully saturated transmitters operating in their most power efficient mode. After amplification and transmission, the signals are multiplexed in the air as opposed to multiplexing before amplification that allows for more efficient amplification as well. In a preferred embodiment, the system has two or more transmitting antennas, and the method comprises: (a) generating a first signal of a first carrier frequency and a second signal of a second carrier frequency; (b) transmitting the first signal of a first carrier frequency on a first antenna and the first signal of a second carrier signal on a second antenna for a predetermined time period; and (c) transmitting a second signal of the second carrier frequency on said first antenna and a second signal of the first carrier frequency on the second antenna for the predetermined time period. Preferably, the signals are transmitted using an amplifier that is essentially fully saturated.

摘要： An offset correction analogic circuit capable of compensating the offset of a digital baseband is described. The circuit comprises analog means to receive an output differential signal issued from a differential signal path. The differential signal path may be a baseband filter as used in digital communication systems. The baseband filter inputs an input differential signal having an offset to be compensated. The output differential signal is fed into an analog integrator to generate a pulsed signal either on a first output line or on a second output line according to the polarity of the output differential signal. The pulsed signal is then integrated into a switched capacitor and a differential compensation offset signal is issued. The frequency of the pulsed signal is preferably proportional to the voltage value of the output differential signal. The compensation offset signal may be summed with the input differential signal into a summing circuit.
