ABSTRACT:
A transmitter (200) for transmitting radio signals comprising a digital signal source (102), a compensation unit (104), two digit al-to-analogue converters (106) and (108), an analogue modulator (110), an amplifier (112) an antenna (114) connected to the amplifier (112), the transmitter further comprises a front-end unit (220) connected to an estimator (230). Said front-end unit (220) comprises a mixer operably (302) connected to a local oscillator (304), an analogue-to-digital converter (306) for processing signal received from the mixer (302), a first digital filter (308) for converting signal received from the analogue-to-digital converter (306) to a baseband signal, an adaptive digital filter (310) operable to time-synchronise its output signal (z(k)) to a reference signal (r(k)) and to remove linear distortions from the signal received from the first digital filter.
