A Multitask Learning Framework For Pilot Decontamination In 5g Massive Mimo, Crallet Victor Sep 2023

A Multitask Learning Framework For Pilot Decontamination In 5g Massive Mimo, Crallet Victor

Tanzania Journal of Engineering and Technology (TJET)

Reference signals enable the acquisition of channel state information (CSI) for purposes such as channel estimation, beam selection, precoding, and symbol detection in 5G massive multiple-input multiple output (MAMIMO) systems. Eventually, as more and more users and cells are added, orthogonal reference signals become few which leads to pilot contamination. Pilot contamination limits the performance and occurs when non-orthogonal reference signals occupy time-frequency resources that are alike. Learning-based techniques have been proposed to alleviate it. However, each can only learn to perform a single task namely pilot assignment, power allocation, pilot design, or de-noising for pilot decontamination. In addition, each …

3d Printed Composite Structures For Bone Repair And Drug Delivery Application, Innocent J. Macha

Tanzania Journal of Engineering and Technology (TJET)

Due to the increase in traffic accidents, industrial contingencies, and natural disasters, there is a high demand for bone regeneration biomaterials. Although bone can regenerate and self-repair, it is difficult to do so when the defect area exceeds the critical repair area due to trauma, tumour resection, or congenital diseases. The traditional methods for bone repair are autograft, allograft, and xenograft. However, these methods have flaws and limitations, such as complications in the donor bone area, a limited number of donors, rejection, and infectious diseases. However, in recent years, the use of additive manufacturing technologies in bone tissue engineering has …
