Abstract
The present invention relates to radio transmission of bursts in for example a TDMA cellular radio system. The burst starts with a ramping up period, ends with a corresponding ramping down ramping down period and with the pay-load information therebetween. The ramp form is created in a ramp generator () which gives a multiplication value to multiply the digital information to be transmitted in multipliers (). The multiplied values are converted into analogue form and amplified before being transferred to the antenna (). Output power and temperature of the transmitting equipment are measured () and used to update the output power levels during the next burst.
