Abstract: This paper investigates channel estimation for linear time-varying (LTV) wireless channels under double sparsity, i.e., sparsity in both the delay and Doppler domains. An on-grid ...
Abstract: We develop a modulation recognition algorithm for orthogonal frequency division multiplexing (OFDM) signals in decode-and-forward (DF) full-duplex (FD) cooperative broadcast systems. In such ...
This project presents a neural network based approach for channel estimation in DC-biased Optical Orthogonal Frequency Division Multiplexing (DCO-OFDM) systems, commonly used in Visible Light ...
