Deep Channel Estimator for Superimposed Pilot-Aided MIMO-OFDM Systems
Pilot overhead is a bottleneck for improving spectral efficiency in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. To alleviate this issue, superimposed pilot (SIP)-aided transmissions have been widely studied. However, channel estimation under SIP remains challenging due...
