Discrete-Circulant-Transform Spread OFDM for Bandwidth-Limited VLC Systems

We propose and investigate discrete-circulant transform spread orthogonal frequency division multiplexing (DCrT-S-OFDM) for bandwidth-limited optical systems. We derive the conditions for optimal designs of DCrT-S-OFDM in the noise limited scenarios and verify its bit error rate advantage over conve...
