Abstract: Joint activity detection and channel estimation is a crucial task in grant-free random access for massive machine-type communications. To enhance communication quality, intelligent ...

Abstract: Reconfigurable intelligent surfaces (RISs) have emerged as a key enabling technology for next-generation (xG) Internet-of-Things (IoT) networks operating in high-frequency bands such as ...

A discrete-time signal is a sequence of numbers defined only at integer values of time. Addition combines two signals sample by sample. y[n] = x₁[n] + x₂[n] Used in mixing and superposition of signals ...
