An efficient method to measure reliability of underwater acoustic communication links

Journal of Ocean Engineering and Science, 2016
We consider the problem of evaluating the reliability of underwater acoustic communication (UWAC) systems. Reliability is a requirement for any communication system and is often defined as the probability to achieve a target bit error rate. Evaluation of

Closed‐Form Approximation of Average Error Probability With Finite‐Blocklength Coding Over Lognormal Wireless Communication Links

IET Communications, Volume 20, Issue 1, January/December 2026.
This work extends the Polyanskiy‐Poor‐Verdu (PPV) framework to lognormal wireless links. Specifically, the paper derives a closed‐form approximation for the average error probability under lognormal distribution, effectively generalizing the PPV analysis beyond the additive white Gaussian noise assumption.

Energy‐Efficient Element Selection in RIS‐Assisted Backscatter Communication Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper investigates energy‐efficient reconfigurable intelligent surface (RIS) assisted ambient backscatter communication systems with energy‐harvesting tags. A low‐complexity RIS element selection strategy is developed to satisfy both energy‐harvesting and signal‐to‐interference‐plus‐noise ratio constraints while minimizing overall power ...

Performance Analysis of Directional Modulation With Finite-Quantized RF Phase Shifters in Analog Beamforming Structure

IEEE Access, 2019
The radio frequency (RF) phase shifter with finite quantization bits in analog beamforming (AB) structure forms quantization error (QE) and causes a performance loss of received signal to interference plus noise ratio (SINR) at the receiver (called Bob).

Computationally Efficient Deep Learning Inference for High‐Rate Beamforming in Millimeter‐Wave Internet of Vehicles

IET Communications, Volume 20, Issue 1, January/December 2026.
ABSTRACT Millimeter‐wave (mmWave) Internet‐of‐Vehicles (IoV) communications rely on large antenna arrays to combat severe path loss and to provide high beamforming gains. However, practical vehicular deployments often adopt analog or hybrid beamforming with constant‐modulus constraints, leading to a highly non‐convex joint beamforming design problem ...
