A Transformer-LSTM Hybrid Detector for OFDM-IM Signal Detection. [PDF]
Entropy (Basel)This paper addresses the signal detection problem in orthogonal frequency division multiplexing with index modulation (OFDM-IM) systems using deep learning (DL) techniques. In particular, a DL-based detector termed FullTrans-IM is proposed, which integrates the Transformer architecture with long short-term memory (LSTM) networks.
