1. transmitter, particularly a kind of mobile radio transmitter is used to produce transmission signals Y (t), and this transmitter comprises:

  • One first modulating device (12), be used for modulating at least one baseband signal I, Q to produce non-compensation transmission signals Y (t) with separately oscillator signal LOQ, LOI, it is characterized in that;

    this transmitter also comprises one second modulating device (14), by with auxiliary oscillator signal 3LOQ, 3LOI modulating baseband signal I, Q, be used for producing represent in fact the compensating signal C (t) that will be compensated at non-compensation transmission signals Y (t) andA substracting unit (18) is used for the transmission signals Y '"'"' that deducts compensating signal C (t) and be used to be delivered to small part compensation from non-compensation transmission signals Y (t) (t).
