On Max-SINR Receiver for Hexagonal Multicarrier Transmission Over Doubly Dispersive Channel
, 2013 In this paper, a novel receiver for Hexagonal Multicarrier Transmission (HMT) system based on the maximizing Signal-to-Interference-plus-Noise Ratio (Max-SINR) criterion is proposed. Theoretical analysis shows that the prototype pulse of the proposed Max-

IET Power Electronics, Volume 19, Issue 1, January/December 2026.The proposed TB‐SCMLI is able to provide seven levels of output voltage by balancing the voltage of two capacitors with the given control logic. The various SCMLIs are evaluated to determine the contribution of the suggested TB‐SCMLI topology's merits and downsides.

Multicarrier 16QAM transmission with diversity reception
Electronics Letters, 1996 A 96 multicarrier 16QAM transmitter and a diversity receiver for 3.072 Mbit/s data transmission are described. Pilot symbol aided (PSA) coherent detection is applied. A laboratory experiment demonstrates that an irreducible bit error rate (BER) of 10-3 can be achieved at the RMS delay spread τrms = 6.3 µs under frequency selective Rayleigh fading when ...

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers
