In this paper, we consider channel estimation for orthogonal frequency division multiplexing (OFDM) systems when both the transmitter and receiver suffer from in-phase and quadrature-phase (I/Q) ...

Fractional OFDM based transmitter and receiver for time/frequency multiplexing in gridless, ... Using reconfigurable wavelength selective switches, we demonstrated open eye diagrams, and performance ...

OFDM transmitter and receiver are implemented in GNU Radio on two different computer systems. GRC files for transmitter and receiver are availabel with name Tx_Ofdm.grc and Rx_Ofdm.grc. Generated OFDM ...
