A LINC amplifier utilizing digital signal processing applied to a DAMPS system
This paper is about implementing a LINC amplifier utilizing DSP in a DAMPS wireless system. First, the theory behind LINC amplifiers is presented. Then the I-Q representation of signals is studied. Followed by a look at pi/4 QPSK schemes. Then, wepsilall show how to apply a LINC amplifier to a pi/4 QPSK modulation scheme in a digital environment, and give the equivalent RF circuit. The digital concerns related to that procedure are then studied. Finally, a prototype system will be presented. Computer simulation of this system and the proposed implementation are both presented.
