It is now well known that employing channel adaptive signaling in wireless communication
systems can yield large improvements in almost any performance metric. Unfortunately …

Recent results establish the optimality of interference alignment to approach the Shannon
capacity of interference networks at high SNR. However, the extent to which interference can …

In this paper, the problem of designing linear precoders for fixed multiple-input-multiple-
output (MIMO) receivers is considered. Two different design criteria are considered. In the …

Tight frames, also known as general Welch-bound-equality sequences, generalize
orthonormal systems. Numerous applications-including communications, coding, and …

Recent results establish the optimality of interference alignment to approach the Shannon
capacity of interference networks at high SNR. However, the extent to which interference can …

The application of mathematical analysis to the study of wireless ad hoc networks has met
with limited success due to the complexity of mobility and traffic models, the dynamic …

This paper is focused on code-domain non-orthogonal multiple access (CD-NOMA), which
is an emerging paradigm to support massive connectivity for future machine-type wireless …

We consider the uplink of a multiuser system where the transmitters as well as the receiver
are equipped with multiple antennas. Each user multiplexes its symbols by a linear precoder …

We present sets of spreading sequences that are specifically designed to suit a belief-
propagation multiuser detection structure, recently presented for overloaded system …

The ubiquitous trend to “go wireless” is a symbol of our need for independence and
flexibility. To allow for such an “all-wireless” world, large amounts of information with widely …
