论文摘要
在这封信中，我们研究了使用实用接收器的矩形脉冲正交时间频率空间（OTFS）调制的错误性能。具体来说，我们考虑了接收器RF前端的必需带通滤波器，该滤波器在现有作品中被忽略了。我们分析了矩形脉冲对实用OTFS接收器性能的影响，并得出了延迟多普勒（DD）域中干扰的确切形式。我们证明，DD域某些区域中的传输信息符号受到严重污染。结果，接收器错误性能有一个错误地板，在实用系统中，需要解决此类OTFS波形的问题。
In this letter, we investigate error performance of rectangular pulse-shaped orthogonal time frequency space (OTFS) modulation with a practical receiver. Specifically, we consider an essential bandpass filter at receiver RF front-end, which has been ignored in existing works. We analyse the effect of rectangular pulses on practical OTFS receiver performance, and derive the exact forms of interference in delay-Doppler (DD) domain. We demonstrate that the transmitted information symbols in certain regions of the DD domain are severely contaminated. As a result, there is an error floor in the receiver error performance, which needs to be addressed for such OTFS waveform in practical systems.
