摘要:

本文提出了一种用于多层传输中叠加导频(SIP)的基于干扰消除的神经接收机,其中数据和导频在相同的时频资源上非正交叠加。具体而言,为了处理多层传输下SIP的层内和层间干扰,该神经接收机利用了叠加符号辅助信道估计的干扰消除技术,并在发射端预设计了导频码分正交机制。此外,为了分别解决跨厂商协作的复杂性问题以及实际部署中的泛化问题,本文还提供了一种基于恒定导频功率比的固定SIP(F-SIP)设计,以及针对不同调制编码方案(MCSs)和传输层的可扩展机制。仿真结果表明,与现有方案相比,所提方案在块错误率和吞吐量性能上具有优越性。

英文摘要:

In this paper, an interference cancellation based neural receiver for superimposed pilot (SIP) in multi-layer transmission is proposed, where the data and pilot are non-orthogonally superimposed in the same time-frequency resource. Specifically, to deal with the intra-layer and inter-layer interference of SIP under multi-layer transmission, the interference cancellation with superimposed symbol aided channel estimation is leveraged in the neural receiver, accompanied by the pre-design of pilot code-division orthogonal mechanism at transmitter. In addition, to address the complexity issue for inter-vendor collaboration and the generalization problem in practical deployments, respectively, this paper also provides a fixed SIP (F-SIP) design based on constant pilot power ratio and scalable mechanisms for different modulation and coding schemes (MCSs) and transmission layers. Simulation results demonstrate the superiority of the proposed schemes on the performance of block error rate and throughput compared with existing counterparts.
