Low-Complexity Differential Spatial Modulation Schemes for a Lot of Antennas
IEEE Access, 2020 Spatial modulation (SM) uses a single antenna for transmission each time to avoid synchronization and interferences among transmitter antennas, and differential SM (DSM) is a kind of SM technique that does not need pilot symbols and channel estimation ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This work proposes a conditional diffusion model framework for high‐fidelity 3D reconstruction from sparse multibaseline circular synthetic aperture radar (CSAR) data, addressing challenges of low vertical resolution, geometric blur and artefacts. The method integrates a dual‐path 3D U‐Net with cross‐attention to fuse coarse reconstruction features ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper presents a long‐time coherent integration framework for bistatic space‐based early warning radar (SBEWR) systems, combining both intra‐frame and inter‐frame integration. To address challenges such as range and Doppler cell migration, phase inconsistencies and strong clutter, the proposed method first applies space‐time adaptive processing ...

Differentially Encoded LDPC Codes—Part I: Special Case of Product Accumulate Codes
EURASIP Journal on Wireless Communications and Networking, 2008 Part I of a two-part series investigates product accumulate codes, a special class of differentially-encoded low density parity check (DE-LDPC) codes with high performance and low complexity, on flat Rayleigh fading channels.

Spectral-Centroid-Based Non-Coherent Detection for Chaos Shift Keying
Applied SciencesClassical coherent chaos shift keying (CSK) provides certain physical-layer advantages by exploiting chaotic waveforms, but it relies on fragile chaos synchronization, which is difficult to maintain in multipath fading channels.

Comparison between Coherent and Noncoherent Receivers for UWB Communications
EURASIP Journal on Advances in Signal Processing, 2005 We present a comparison between coherent and noncoherent UWB receivers, under a realistic propagation environment, that takes into account also the effect of path-dependent pulse distortion. As far as coherent receivers are concerned, both maximal ratio

Differential Faster-Than-Nyquist Signaling
IEEE Access, 2018 In this paper, we propose a novel differential faster-than-Nyquist (DFTN) signaling concept that allows us to dispense with any channel estimation at the receiver, while benefiting from a rate boost specific to faster-than-Nyquist (FTN) signaling.

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization
EURASIP Journal on Wireless Communications and Networking, 2008 This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection.
