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

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