System and method for performing control of engaging in ring modulated signals with offset and band limited

摘要

The present invention relates to a method for effecting control of engaging in ring of modulated signals with offset and band limited, in order to include a transmitter that uses a power amplifier (HPA) non linear (104) with high energy efficiency without resulting extends so Chin you of the spectrum of transmitted signal.In the system of transmission is an integrated block (102) which performs a modulation of the magnitude (mm) of each modulated symbol that is generated by the block (101) so as to ensure the limitation of dynamic range of signal at the exit of the filter (103) for limiting the bandwidth of the signal to transmit R,Which subsequently allows the use of the amplifier (104) without the power spectrum of the transmitted signal (i.e. signal obtained at the exit (105) is visibly affected.
