A typical transmitter design requirement is for the high power amplifier to be operated in saturation. The LINC approach described here employs a polyphase-coded FM (PCFM) waveform that is able to overcome this saturated amplifier distortion to greatly improve the spectral containment of the transmitted waveform. A two stage optimization process involving simulation and hardware-in-the-loop routines is used to create the final PCFM waveform code. | Keywords/Search Tags: | LINC, Waveform | | Related items |
