Abstract Low-density multiple-input multiple-output code (LDMC) can reduce the complexity of tree-search detection in MIMO systems. In this paper, we present a new modified progressive edge-growth (PEG) algorithm to construct large girth LDMCs, which

This paper proposes a novel location-based multi-group multicast framework, which is termed non-orthogonal multiple access (NOMA)-assisted multi-region geocast. This novel spectrum sharing framework exploits the NOMA technology to realize the simulta

This paper investigates the effect of multiuser gain provided by the secondary user selection on the secrecy performance of the primary users. We first propose a simple scheme where the user with the minimal interference channel is selected, and deri

Abstract Precoding techniques can be used in multiple input multiple output (MIMO) system to assign resources such as power and information optimally. This paper is concerned with limited feedback in precoded orthogonal space time block code (OSTBC)

To improve the sum-rate (SR) and the outage probability of the dual-hop relay system, a novel two-stage power allocation scheme with non-orthogonal multiple access is proposed. In this scheme, after the reception of the superposition coded symbol wit

In this paper, we present a complex Hadamard matrix-aided generalized space shift keying (HSSK) modulation scheme, which introduces complex-Hadamard-based signal vectors at the transmitter to provide higher spectrum efficiency than generalized space

For a given base graph, the lifted graph can be obtained by a copy-and-permute procedure. If the permutation is cyclic, the lifted graph corresponds to a quasi-cyclic (QC) protograph low-density parity-check (LDPC) code. The girth of the QC protograp

In this article, we present a black-hole-aided deep-helix (bh-dh) channel model to enhance information bound and mitigate a multiple-helix directional issue in Deoxyribonucleic acid (DNA) communications. The recent observations of DNA do not match wi

In this paper, we characterise the joint interference alignment (IA) and power allocation strategies for a K-user multicell multiple-input multiple-output (MIMO) Gaussian interference channel. We consider a MIMO interference channel with blind-IA thr
