Recovery of the support of a block K-sparse signal x from a linear model y= Ax+ v, where A is a sensing matrix and v is a noise vector, arises from many applications. The block …
In this paper, we study the problem of\textit {activity detection}(AD) in a massive MIMO setup, where the Base Station (BS) has $ M\gg 1$ antennas. We consider a block fading channel …

Sparse device activity detection for machine-type communications has attracted increasing attention in recent studies. However, most of the previous works focus on the single-cell …
In this paper, we propose a transmission control scheme and design an approximate message passing (AMP) algorithm for the joint user identification and channel estimation …
Recently, non-orthogonal codes have been advocated for IoT massive access. Activity detection has been demonstrated to entail common support recovery in a jointly sparse …
The next wave of wireless technologies will prolifer-ate in connecting sensors, machines, and robots for myriad new applications, thereby creating the fabric for the Internet of Things …
