Concurrent Multiband Digital Outphasing Transmitter Architecture Using Multidimensional Power Coding
Publikováno v:
IEEE Transactions on Microwave Theory and Techniques. 63:598-613
All-digital outphasing transmitter architecture using multidimensional power coding (MDPC) is proposed for noncontiguous concurrent multiband transmission with a high power efficiency. MDPC transforms multiband digital baseband signals into multibit
