Abstract
A relative delay between analog R.F. output signals of a plurality of digital radio transmitters in a digital radio transmitter system is controlled. At least one interface receives delay information for each transmitter. A processing unit determines the relative delay between the output signals based on the received delay information. An adjuster adjusts in the digital domain the absolute delay of at least one of the radio transmitters in accordance with the determined relative delay.
