Joint Model and Data Driven Receiver Design for Data-Dependent Superimposed Training Scheme with Imperfect Hardware
Chaojin Qing, Lei Dong, Li Wang +2
Data-dependent superimposed training (DDST) scheme has shown the potential to achieve high bandwidth efficiency, while encounters symbol misidentification caused by hardware imperf…
Enhanced ELM Based Channel Estimation for RIS-Assisted OFDM systems with Insufficient CP and Imperfect Hardware
Chaojin Qing, Li Wang, Lei Dong +1
Reconfigurable intelligent surface (RIS)-assisted orthogonal frequency division multiplexing (OFDM) systems have aroused extensive research interests due to the controllable commun…
Label Design-based ELM Network for Timing Synchronization in OFDM Systems with Nonlinear Distortion
Chaojin Qing, Shuhai Tang, Chuangui Rao +3
Due to the nonlinear distortion in Orthogonal frequency division multiplexing (OFDM) systems, the timing synchronization (TS) performance is inevitably degraded at the receiver. To…
ELM-based Frame Synchronization in Nonlinear Distortion Scenario Using Superimposed Training
Chaojin Qing, Wang Yu, Shuhai Tang +2
The requirement of high spectrum efficiency puts forward higher requirements on frame synchronization (FS) in wireless communication systems. Meanwhile, a large number of nonlinear…
