In the heterogeneous network (HetNet) employing downlink non-orthogonal multiple access (NOMA), we focus on the non-convex optimization problem to optimize the spectral efficiency (SE) while the users satisfy the quality-of-service (QoS) requirement.

Cyclic interleaved frequency division multiplexing (CIFDM), a variant of IFDM, has recently been proposed. While CIFDM employs cyclic interleaving at the transmitter to make multipath components resolvable at the receiver, the current approach of mat

Due to the constraints of the satellite communication systems, the receiver signal processing was carried out in the time domain, which made traditional channel equalization algorithms face the challenge of high-dimensional matrix inversion. Taking f

Abstract In this work, we propose a multiple feedback-based successive interference cancellation (SIC) scheme for an ultra-dense Internet of Things (IoT) device network. Non-orthogonal multiple access (NOMA) enables massive connectivity with improved

Symbiotic Radio Networks (SRNs) have emerged as an important communication protocol to solve the increasing energy demand and spectrum resource shortage. However, the low bit rates of the devices working in SRNs during backscatter communication, wher

With the boom of the communication systems on some independent platforms (such as satellites, space stations, airplanes, and vessels), co-site interference is becoming prominent. The adaptive interference cancellation method has been adopted to solve

This paper presents a novel method for identification of the sub-system parameters of a Wiener-Hammerstein Nonlinear (WHNL) system that is used for modeling RF Power Amplifier characteristics. The proposed method first isolates the overall linear sys

In this paper, we propose a correlation-based background linearity calibration technique to digitally correct the bit weights in successive approximation register (SAR)-assisted analog-to-digital converters (ADCs). Unlike typical dithering-based cali
