Abstract: Hybrid non-orthogonal multiple access (NOMA) has been widely explored to enhance system performance by integrating NOMA with frequency-division multiple access (FDMA) or time-division ...
The use of the active ingredient 3,4-methylenedioxy-N-methylamphetamine (MDMA), commonly known as "ecstasy", to support psychotherapy for mental illnesses such as post-traumatic stress disorder is ...
Summary: Researchers developed three new MDMA variants (ODMA, TDMA, and SeDMA) that retain the therapeutic benefits while reducing side effects. These compounds affect mood-regulating brain structures ...
GLONASS satellites traditionally use L1 and L2 frequency division multiple access (FDMA) signals. FDMA is characterized by a different transmit frequency for each satellite. Newer satellite ...
LDACS-Abstract-TDMA-MAC is part of the LDACS-Greedy-K-Hop-Simulator project. It implements an abstract version of the MCSOTDMA MAC protocol designed for LDACS A2A communications. This component models ...
