Downlink and uplink MIMO-SCMA System
Journal of Physics: Conference Series, 2020 Abstract Sparse code multiple access is a promising multiple access technology capable of increasing the spectral efficiency of communication systems. Another technology that can improve the spectral or power efficiency is multiple input multiple output. Combining both technologies offers an advantage over classic approaches.

FEBS Open Bio, Volume 15, Issue 3, Page 490-505, March 2025.Scientific literacy (SL) skill development and retention in kinesiology students was assessed in a research methods course taught using a flipped classroom approach. SL skills improved (16.3%, n = 57) with higher SL skill development positively correlated with final grade (r = 0.526).

Low-complexity hybrid interference cancellation for sparse code multiple access
EURASIP Journal on Wireless Communications and Networking, 2022 Sparse Code Multiple Access (SCMA) is one of Non Orthogonal Multiple Access (NOMA) candidates for 5G, the fifth generation mobile network. Multiple overlapped blocks of SCMA code are transmitted per frequency layer which compels the receiver to cancel ...

Meteorological Applications, Volume 32, Issue 2, March/April 2025.The impact of rainfall and farmers' crop selection under rainfall aberration was assessed using the long‐term historical datasets on rainfall and crop production datasets of Karnataka, a rainfed state of India. A direct link between rainfall and area under different crops was observed, and was not true for many crops since there was a crop shift ...
