This paper investigates filter bank multicarrier with quadrature amplitude modulation (FBMC/QAM) as a waveform candidate for multi-user multiple-input single-output communication. A transceiver design for the downlink transmission is developed, following which the signal-to-interference-plus-noise ratio is derived to q...

An orthogonal affine-precoded superimposed training sequence (AP-STS)-based framework is conceived for cyclic prefix (CP)-assisted multiple-input multiple-output (MIMO) direct-current-biased orthogonal time frequency space (DCOOTFS) visible light communication (VLC) links using arbitrary transmit-receive pulse shaping...

A multipath CIR estimator is proposed, followed by sparse frequency-domain (FD) signal detection, which harnesses the simultaneous-sparsity innate in the multipath CIR and FD signals across measurement vectors, conceived for optical OFDM (O-OFDM) utilized for visible light communication (VLC) systems having reduced pea...

Integrated sensing and communication (ISAC) has emerged as a key paradigm for unifying radar sensing and wireless communications within a shared hardware and spectral framework. In parallel, ambient backscatter communication (AmBC) has gained attention as a low-power solution for enabling passive connectivity by modula...
