Delay control in a digital radio transmitter system

摘要

A device (200) for controlling a relative delay between analog R.F. output signals of a plurality of digital radio transmitters (102, 104) in a digital radio transmitter system (100) is described. The device (200) comprises at least one interface (206a, 206b) for receiving delay information, a processing unit (206) for determining the relative delay between the output signals based on the received delay information and an adjusting system for adjusting in the digital domain the absolute delay of at least one of the radio transmitters (102, 104) in accordance with the determined relative delay. The invention further relates to a method for controlling a relative delay between analog R.F. output signals of a plurality of digital radio transmitters (102, 104). <IMAGE>
