Blind Channel and Data Estimation Using Fuzzy Logic-Empowered Opposite Learning-Based Mutant Particle Swarm Optimization. [PDF]
Comput Intell Neurosci, 2018 Multiple‐input and multiple‐output (MIMO) technology is one of the latest technologies to enhance the capacity of the channel as well as the service quality of the communication system. By using the MIMO technology at the physical layer, the estimation of the data and the channel is performed based on the principle of maximum likelihood.

Optimizing Nonlinear Distortion and Interference in MC‐CDMA Receivers Employing Deep Neural Networks
Mobile Information Systems, Volume 2023, Issue 1, 2023., 2023 Systems that employ multicarrier code division multiple access, commonly known as MC‐CDMA, produce outstanding results in terms of both the performance of the system as a whole and the efficiency with which it uses the spectrum. However, multiple access strategies are susceptible to interference despite their high spectrum efficiency. This work aims to

Journal of Robotics, Volume 2022, Issue 1, 2022., 2022 It is demonstrated that the fully parallel turbo decoding algorithm can achieve an approximate error correction decoding performance when 36 iterations are used and when the log‐map algorithm with 6 iterations is used. By comparison, it is shown that it can achieve much higher decoding rates than the log‐map algorithm for various frame lengths of LTE ...
