IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

IET Communications, Volume 20, Issue 1, January/December 2026.This paper develops a focal‐curvature‐aware near‐field ISAC framework for a distributed parallel STAR‐RIS‐assisted system employing a cylindrical‐array base station. Exact spherical‐wave propagation and reciprocal wideband sensing are used to derive an energy–curvature relationship linking focal energy, focal‐coherence curvature, EFIM, and PEB ...

Deep‐Learned Channel Estimation for MIMO‐OFDM System by Exploiting Frequency‐Space Correlation
Electronics Letters, Volume 62, Issue 1, January/December 2026.In massive MIMO–OFDM systems, accurate channel state information acquisition is vital for reliable transmission. Traditional methods fail to fully exploit sparse channel correlation, so an attentive residual autoencoder network is proposed. It uses an autoencoder with attention and residual connections to capture frequency–space correlation, and ...
