English(EN) ReFLEX: Length-Generalizable CSI Denoising for MIMO-OFDM via Relative-Frequency Bias

ReFLEX模型改进了MIMO-OFDM系统的信道状态信息去噪

研究人员开发了ReFLEX,这是一种新颖的Transformer模型,用于在具有可变资源块分配的MIMO-OFDM系统中去噪信道状态信息(CSI)。该模型在其注意力机制中使用了相对频率位置偏差,允许单个检查点在无需重新训练的情况下处理未见的资源块长度。在模拟中,ReFLEX在去噪精度方面表现出显著的改进,并降低了NR PUSCH/UL-SCH场景下的块错误率阈值。 AI
