Abstract
In a radio transmission output control circuit, a modulating circuit modulates signals to be sequentially transmitted in consecutive time slots at predetermined timings. A data generating circuit generates, when one time slot is being transmitted, data meant for another time slot to be transmitted subsequently. The data include output control information for the subsequent time slot, and the deviation of the output level of the subsequent time slot. The data generating circuit outputs the data at a transmission timing assigned to the subsequent time slot. A level control circuit controls the output level of the subsequent time slot on the basis of the data from the data generating circuit. With this configuration, it is possible to execute control over a transmission output signal rapidly.
Claims6
A radio transmission output control circuit comprising:
- modulating means for modulating signals to be sequentially transmitted in consecutive time slots at predetermined timings;
- control data generating means for generating, when one of the consecutive time slots is being transmitted, control data for controlling an output level of a subsequent time slot, and for outputting said control data in response to a transmission timing assigned to said subsequent time slot, said control data being generated and output prior to the start of said subsequent time slot;
- and
- level control means for controlling said output level of said subsequent time slot on the basis of said control data.
