A method of adjusting time alignment of a sampled data stream is disclosed. The method comprises transferring the sampled data stream from a baseband subsystem to a digital interface, transferring the sampled data stream from the digital interface to a digital radio comprising a pulse shaping filter modulator, modulating the sampled data stream by using the pulse shaping filter modulator, and transmitting the modulated sampled data stream. The method further comprises transferring a time adjustment control signal from the baseband subsystem to the digital radio, and the modulating step comprises a step of adjusting, based on the time adjustment control signal, the time alignment of the sampled data stream using a sample resolution. Corresponding computer program product, arrangement, and electronic device are also disclosed.
