This paper considers random multiple access in a network where only a small portion of
users have data to forward and transmit packets in each time slot because the user activity …

In this paper, methods for detection of frequency-hop** spread spectrum (FHSS) signals
from compressive measurements are proposed. Rapid switching of the carrier frequency in a …

This paper proposes a compressed sensing-based random access protocol (CS-RACH),
which is suitable for servicing a large number of machine-type communication devices in …

In this paper we introduce the Cognitive Compressive Sensing (CCS) problem, modeling a
Cognitive Receiver (CR) that optimizes the K projections of a N> K dimensional vector …

This paper considers the channel estimation (CE) and multi-user detection (MUD) problems
in cloud radio access network (C-RAN). By taking into account of the sparsity of user …

Compressed sensing assisted Joint Channel Estimation and Detection (JCED) for
asynchronous Direct-Sequence Code Division Multiple Access (DS-CDMA) system is …

Compute-and-forward (C&F) recently finds new applications in random-access networks
focusing on the single access point (AP) scenario. In this paper, we extend the use of C&F …

In the Cognitive Compressive Sensing (CCS) problem, a Cognitive Receiver (CR) seeks to
optimize the reward obtained by sensing an underlying N dimensional random vector, by …

Conventional collision detection techniques do not provide great accuracy. For example,
one such technique detects collisions based solely on received signal power. According to …

We present a method for separating collided signals from multiple users in the presence of
strong and wideband interference/jamming signal. More specifically, we consider a massive …
