an improved range migration algorithm is proposed, which can effectively increase the utilization of the spectrum for data processing. Finally, an improved method of geographic information-scale ...

Abstract: A major drawback of the orthogonal frequency division multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit power amplifier (PA) and other elements in the ...
