The study integrates dimmable constant weight polar‐coded non‐orthogonal multiple access (CWPC‐NOMA) with orthogonal space‐time block coding (OSTBC) for visible light communication (VLC). The proposed scheme enhances spectral efficiency and reliability while optimizing resource utilization and leveraging transmit diversity.

—In multicarrier code-division multiple-access (MCCDMA), the total system bandwidth is divided into a number of subbands, where each subband may use direct-sequence (DS) spreading and each subband signal is transmitted using a subcarrier frequency.

The impact of high‐power electromagnetic on the power amplifier inside the conductive enclosure has been investigated. By using the finite difference delay modelling numerical method as a stable method followed by the vector fitting method, the electromagnetic problem has become a circuit problem, which allows examining the response of the power ...

A composite co‐assembled dehydropeptide‐based gel is designed for the orthogonal triggered release of doxorubicin and methotrexate. The incorporation of mesoporous silica‐coated gold nanorods and magnetic liposomes within the gel allows for the combined effects of sequential drug release through photothermia and magnetic hyperthermia, resulting in ...
