摘要： A multicarrier transmitting method that includes inputting n input signals, generating carriers corresponding to the n input signals, modulating the carriers into n modulated signals and generating at least one additional signal having a frequency outside band of the n modulated signals. The method also includes adjusting a level and a phase of the generated additional signal, outputting a multiplexed signal by adding up the n modulated signals and the adjusted additional signal, amplifying the multiplexed signal, and then removing the additional signal. The level and the phase of the additional signal are adjusted such that, after predicting a change of a composite vector of the n modulated signals based on an amplitude and a phase of the n carriers, a composite vector obtained after an adding operation can be lower than that before the adding operation when an absolute value of a prediction result exceeds a predetermined level.

摘要： When switching the mode of a power amplifier between compressed mode and uncompressed mode, accurate transmission power control is realized. A transmission power control method includes setting a power setting value of mode to switch to, such that an inter-mode output power error is canceled (equal to step ST21), calculating an intra-mode output power error from the power setting value of the mode to switch to (equal to step ST23), calculating a gain linearity value based on the power setting value of the mode to switch to and an output power error of the intra-mode (equal to step ST24), and resetting the power setting value of the mode to switch to based on the gain linearity value (equal to steps ST25 and 26).

摘要： A transmission circuit switches a bias circuit without allowing a power amplifier to enter a non-bias state. A first bias circuit supplies a first bias signal to a power amplifier, and a second bias circuit supplies a second bias signal to the power amplifier. A first delay circuit delays the switching of an operation of the first bias circuit using a first delay time, and a second delay circuit delays the switching of an operation of the second bias circuit using a second delay time. The first bias circuit and the second bias circuit are both simultaneously operated for a predefined time period, in order to prevent a transistor for amplification from entering a non-bias state when switching an operation mode of the power amplifier.
