초록
In this study, we briefly introduce a novel concept of dual-band polar transmitter design based on digital quadrature modulation techniques for the application of railroad wireless communication (e.g., TRS & GSM-R) to reduce the bandwidth of dual-band PM (phase modulation) signal. We show that the complex signal processing at low frequency effectively utilizes the polar transmitter which is susceptible to the bandwidth of PM signal. Also, we evaluated the zero-crossing rate of two different schemes. There is the remarkable reduction of zero-crossing rate, compared to the conventional scheme.
