Burst transmission apparatus with power amplifying booster and method of boosting burst transmission signals

A burst transmission system comprising:

• a low-power transmitter responsive to a power level command for power-amplifying and outputting transmission signals;
• and
• a booster for further power-amplifying the transmission signals power-amplified by the low-power transmitter such that the power level and waveform of the transmission signals are coincident with or substantially coincident with those of a given reference burst wave, said booster being connectable with the low-power transmitter;
• said booster comprising:
• a power amplifier for power-amplifying transmission signals from said low-power transmitter;
• power amplification control means for controlling the power amplification by the power amplifier such that the power level and waveform of the transmission signals power-amplified by the power amplifier are substantially coincident with those of a given reference burst wave;
• and
• burst control means responsive to control information from an external means for determining and providing the reference burst wave to the power amplification control means;
• said control information containing information specifying a target power level and a reference burst wave generation timing;
• said burst control means generating a reference burst wave such that the power level of the transmission signal amplified by said power amplifier is controlled to a level equal to said target power level and will rise and fall in amplitude with a timing in synchronism with said reference burst wave generation timing.

A boosting method comprising the steps of:

• a first step of determining a reference burst wave based on external control information;
• and
• a second step of power-amplifying transmission signals from a low-power transmitter such that the power level and waveform of the power-amplified transmission signals will be substantially coincident with those of the determined reference burst wave;
• said external control information containing information specifying a target power level and a reference burst wave generation timing;
• said first step further including a step of generating a reference burst wave such that the power level of the transmission signal amplified by said power amplifier is controlled to a level equal to said target power level and will rise and fall in amplitude with a timing in synchronism with said reference burst wave generation timing.
