The emerging massive/large-scale multiple-input multiple-output (LS-MIMO) systems that
rely on very large antenna arrays have become a hot topic of wireless communications …

As we make progress toward the 5G of wireless networks, the bit-per-joule energy efficiency
(EE) becomes an important design criterion for sustainable evolution. In this regard, one of …

Massive multiuser (MU) multiple-input multiple-output (MIMO) is foreseen to be one of the
key technologies in fifth-generation wireless communication systems. In this paper, we …

In this article, we have provided general, comprehensive coverage of the SDR technique,
from its practical deployments and scope of applicability to key theoretical results. We have …

Under the assumptions of symbol-synchronous transmissions and white Gaussian noise, the
authors analyze the detection mechanism at the receiver, comparing different detectors by …

Sphere decoding has been suggested by a number of authors as an efficient algorithm to
solve various detection problems in digital communications. In some cases, the algorithm is …

We present a theory, based on statistical mechanics, to evaluate analytically the
performance of uncoded, fully synchronous, randomly spread code-division multiple-access …

Consideration is given to an asynchronous code-division multiple-access environment in
which receiver has knowledge of the signature waveforms of all the users. Under the …

This paper studies randomly spread code-division multiple access (CDMA) and multiuser
detection in the large-system limit using the replica method developed in statistical physics …

The NP-hard problem of optimizing a quadratic form over the unimodular vector set arises in
radar code design scenarios as well as other active sensing and communication …
