Abstract:
1. A transmitter of a wireless communication system, comprising: a baseband processor configured to generate a baseband digital modulated I-signal and a baseband digital modulated Q-signal; an intermediate frequency (IF) processor configured to up-convert the baseband digital modulated I-signal and the baseband digital modulated Q-signal to generate one digital IF non-constant envelope modulated signal (NC-EMS); a signal component separator configured to separate the digital IF NC-EMS into a first digital IF C-EMS and a second digital IF C-EMS; a radio frequency (RF) processor configured to up-convert the first digital IF C-EMS and the second digital IF C-EMS to generate a first analog RF C-EMS and a second analog RF C-EMS; a power amplifier configured to amplify powers of the first and second analog RF C-EMSs; and an RF combiner configured to combine the first and second analog RF C-EMSs having the amplified powers to generate one combined analog RF C-EMS.
