An Alternative Encoding of the Golden Code and its Low Complexity Detection

open access: yesIEEE Access, 2022
The Golden code is a full-rate full-diversity (FRFD) space-time block code. The encoder of the Golden code takes four complex symbols and generates two pairs of Golden codewords.

The dispersion of superposition coding for Gaussian broadcast channels [PDF]

open access: yes2017 IEEE Information Theory Workshop (ITW), 2017
In this paper, we analyze the performance of superposition coding for Gaussian broadcast channels with finite blocklength. To this end, we adapt two different achievability bounds, the dependence testing and the κβ bounds introduced by Polyanskiy et al. in 2010 to the broadcast setting.

Performance Analysis of Cooperative Relaying Systems With Power-Domain Non-Orthogonal Multiple Access

open access: yesIEEE Access, 2018
Non-orthogonal multiple access (NOMA) is one of the promising radio access techniques in 5G communication networks. In this paper, a cooperative NOMA relaying scheme with two-phase superposition coding is proposed to enhance the performance of NOMA ...

A Cooperative Network Coding Strategy for the Interference Relay Channel. [PDF]

open access: yes, 2012
In this paper, we study an interference relay network with a satellite as relay. We propose a cooperative strategy based on physical layer network coding and superposition modulation decoding for uni-directional communications among users.

Non-Orthogonal Multiple Access With Cooperative Truncated ARQ and Relay Selection

open access: yesIEEE Access, 2019
In this paper, we propose a cooperative truncated automatic repeat-request (T-ARQ)-based non-orthogonal multiple access schemes with relay selection. There are two phases in our proposed scheme.

Guaranteed Performance Region in Fading Orthogonal Space-Time Coded Broadcast Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
Recently, the capacity region of the MIMO broadcast channel (BC) was completely characterized and duality between MIMO multiple access channel (MAC) and MIMO BC with perfect channel state information (CSI) at transmitter and receiver was established.

Cooperative transmission design combining network coding and superposition coding

open access: yesTongxin xuebao, 2012
A joint network coding (NC) and superposition coding scheme was proposed to realize a cooperative transmission.The use of NC was able to improve spectral efficiency over classical decode and forward relaying strategy by relaxing the orthogonality ...
