Error rate analysis for indoor wireless networks [PDF]
An attempt is made to predict the maximum data rates for a typical wireless computer network operating in an indoor frequency-selective environment. To lower the error rates for high-speed data transmission, the impact of techniques such as diversity ...

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
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

Comparative analysis of elementwise reception-algorithms in intersymbol interference channels
Background. Many modern communication-systems work on channels with intersymbol interference. Therefore comparative analysis of elementwise reception-algorithms is topical by work in such channels. Aim.

The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

Tropospheric Propagation Effects Extracted From ADS‐B Messages
This study explores the use of ADS‐B messages to estimate tropospheric effects, effectively isolating atmospheric influences from interference. The approach enables independent lower atmosphere studies and offers a cost‐free supplementary method for satellite applications, benefiting GNSS systems, especially at low elevation angles where multipath and ...

Features of the construction of information transfer system which using two-dimensional signals [PDF]
The article deals with analysis of the causes of intersymbol interference and interchannel interference. It is indicated that physically unrealizable orthogonal bases are used to describe systems and signals. The considered interference occurs due to the

Enhancing FSO‐DWDM Performance Through Compensation Strategies
This study investigates the performance of free space optics (FSO) with dense wavelength division multiplexing (DWDM) systems, focusing on the impact of channel number and compensation strategies on bit error rate (BER). Results show that post‐compensation significantly improves performance, extending the system's range from 3 to 5 km.

A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
