Abstract
With the development of broadcasting technology,the optimization of mid-wave Pulse Duration Modulation(PDMP) transmitter has become the key to improve broadcasting quality. This paper introduces the structure and working principle of sky tuning network and analyzes its infrastructure design. On this basis,the transmitter and the sky tuning network are optimized to improve the performance of the network. In addition,two strategies of impedance matching optimization and anti-interference strengthening are proposed to improve the ability of the network to cope with the complex electromagnetic environment.
