| 英文摘要 | In this paper, we present a novel orthogonal Doppler frequency modulation (ODFM) to meet the challenging requirements of high-mobility communications. Firstly, we revisit the basic concepts of multicarrier modulations (MCMs) and discuss the capability to explore both time and frequency diversity in doubly selective channels for the most popular MCMs. We then illustrate how ODFM maps information symbols into Doppler-frequency domain and converts them into time-delay domain for transmission, where we show ODFM has the potential to exploit both delay space (frequency) and Doppler space (time) diversity. Specifically, we propose two types of ODFM schemes using the conventional time-frequency domain orthogonal pulses (TFOP-ODFM) and the novel delay-Doppler domain orthogonal pulses (DDOP-ODFM). We give exact channel input-output relations (IORs) in the Doppler-frequency domain of these two ODFM schemes and show their properties in efficient channels, implementation complexity, and others. Subsequently, we simulate the performance of these ODFM schemes with other MCMs, such as orthogonal frequency division multiplexing (OFDM), and orthogonal time frequency space (OTFS) modulation. In particular, we investigate the performance of the TFOP-ODFM in the physical downlink shared channel of the Five-Generation New Radio (5G NR) link, where TFOP-ODFM show better performance than OFDM and OTFS. |
