Summary: There is a growing interest in using photoplethysmography (PPG) for continuous monitoring of cardio-respiratory signals in order to diagnose cardiovascular diseases early. This study presents a novel pulse oximeter that uses three different light wavelengths simultaneously to optimize heart rate measurements and continuous assessment of oxygen saturation. The device is based on a Single-Photon Avalanche Diode (SPAD) with very short deadtime to acquire all the wavelengths of interest in transmission mode.

Summary: A circuit-simulation-based method is used to predict the thermally-induced bit error rate of superconducting Single Flux Quantum logic circuits. The method evaluates the effective noise bandwidth and reveals that the actual bit error rate is lower than simplistic estimates based on isolated devices.

Summary: This article presents a performance analysis and comparison of turbo codes using short blockchains. Different types of interleavers are introduced, and their impact on turbo codes, especially for short block lengths, is studied. The performance is evaluated based on bit error rate, with lengths ranging from 64 to 512 bits. A new interleaver based on Duffing chaotic maps is proposed, showing excellent performance for 64 bits.

Summary: Federated edge learning (FEEL) is a popular framework that collaboratively trains a global learning model across multiple distributed edge devices, overcoming the limitation of centralized machine learning. To address the issue of communication cost in FEEL, the SignSGD scheme has been proposed, using one-bit gradient quantization with majority vote. However, the performance of one-bit aggregation is affected by wireless propagation error. In this work, we propose a reconfigurable intelligent surface (RIS)-aided communication optimization scheme to alleviate the negative influence of communication error on SignSGD-based FEEL.

Summary: This letter proposes a method to estimate the performance of LoRa in heavy multipath channels using approximations. By analyzing the interference caused by path overlapping quantitatively, the authors derive simple approximations for bit error rate in both coherent and non-coherent detections. They verify their expressions through Monte Carlo simulations with a realistic indoor industrial scenario model. Performance comparison results demonstrate that a high spreading factor can lead to severe multipath overlap and reduce the bit error rate.
