Abstract

The orthogonal time-frequency space (OTFS) modulation has gained significant attention, due to its robust performance in high-speed mobile environment. In this correspondence, we develop a novel approach wherein delay-Doppler grid symbols into vectors are organized according to their Doppler index for OTFS. A novel detection algorithm is proposed in the Doppler transform domain, which offers lower complexity and better bit error rate (BER) performance compared to existing OTFS detection algorithms. In addition, considering the superior performance of short-block polar codes, we integrate them to further enhance the performance. Simulation results validate the performance advantages of the proposed algorithm over existing benchmarks in terms of BER for OTFS. Specifically, BER performance can be improved by at least 1 dB.

低复杂度极化编码迭代OTFS接收机

正交时频空间（OTFS）调制由于其在高速移动环境中的鲁棒性而受到广泛关注。在这种通信中，我们开发了一种新的方法，其中延迟多普勒网格符号根据其多普勒指数组织成矢量。提出了一种新的多普勒变换域检测算法，该算法比现有的OTFS检测算法具有更低的复杂度和更好的误码率（BER）性能。此外，考虑到短块极性码的优越性能，我们将它们集成在一起以进一步提高性能。仿真结果验证了该算法在OTFS的误码率方面优于现有基准测试的性能优势。具体来说，误码率性能可以提高至少1db。
