在美國數位廣播中,已提出HD Radio AM系統,此系統在 AM 頻帶同時傳送數位廣播訊號。因此本論文探討如何讓 AM 跟數位廣播彼此不互相干擾,另外研究 AM 訊號對數位廣播所造成的時間同步干擾,並提出方法去克服問題。最後將理論實作在FPGA上
Hybrid In-Band on-Channel (HIBOC) digital audio broadcasting (DAB) simultaneously with analog amplitude modulation (AM) has been proposed as a compatible solution to digital audio broadcasting in the AM band. Since some of the transmitted digital data will be conveyed within an existing (broadcasting) analog AM band, self-in-band interferences (SII) exists in the HIBOC AM system. Here we will discuss how to solve SII, and how to solve symbol synchronization error from analog audio signals interferences. Finally, we implement the algorithm by using FPGA.
