Deep Learning for Joint Narrowband Interference Cancellation and Soft Demodulation in OFDM Systems
Two convolutional neural networks (NBI-CNet and LLR-CNet) jointly estimate and cancel multi-tone narrowband interference in OFDM systems and whiten non-Gaussian residuals for LDPC decoding, eliminating error floors at lower complexity than iterative compressed-sensing baselines.
