Wireless-powered Cooperative Spectrum Sharing Networks with Full-duplex and NOMA Transmissions
International Journal of Information and Communication Technology Research, 2019 We consider a cooperative spectrum sharing non-orthogonal multiple access (NOMA) network, where a secondary transmitter assists transmission from a primary transmitter to a primary receiver with poor channel conditions, and at the same time transmits to ...

Spectral Efficiency Analysis for Bidirectional Dynamic Network With Massive MIMO Under Imperfect CSI
IEEE Access, 2018 To cope with the exploding demand for higher data rate and the heavier asymmetry of downlink (DL) and uplink (UL) traffic, dynamic time-division duplex (DTDD) has been proposed, where the time resources can be adjusted dynamically between DL and UL ...

Universal Linear Precoding for NBI-Proof Widely Linear Equalization in MC Systems
EURASIP Journal on Wireless Communications and Networking, 2008 In multicarrier (MC) systems, transmitter redundancy, which is introduced by means of finite-impulse response (FIR) linear precoders, allows for perfect or zero-forcing (ZF) equalization of FIR channels (in the absence of noise).

Successive interference cancellation receiver algorithms for uplink STBC coded MC-CDMA systems
Tongxin xuebao, 2006 A QR decomposition based and a minimum mean square error （MMSE） based successive interference cancel-lation receiver algorithms were proposed for the uplink of space-time block coded multi-carrier code division multiple access （MC-CDMA） systems.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT With the depletion of energy resources and the vigorous development of renewable energy technologies, the demand for efficient energy storage technologies has become increasingly urgent. Dielectric ceramics feature ultrafast charge–discharge speed, but low energy density and inferior efficiency hinder device miniaturization.
