EURASIP Journal on Wireless Communications and Networking, 2017 In this paper, we focus on the design of a reliable communication scheme for generic 5-node wireless butterfly networks (WBN). Since the WBN represents a natural extension of the basic two-way relay communication channel, we follow the paradigm of ...

Analysis of fast sparse superposition codes [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 Sparse superposition codes with a fast adaptive successive decoder for the additive white Gaussian noise channel were introduced last year by the authors, along with presentation of reliability at rates approaching capacity. The present work presents ingredients of the distributional analysis of the decoder.

Results in Physics, 2023 Because the ohmic loss of metal materials affects the transmission efficiency of metasurface, we design a transmission-type all-dielectric coded metasurface element structure based on the principle of Pancharatnam-Berry geometric phase.

On the Error-Reducing Properties of Superposition Codes
2023 XVIII International Symposium Problems of Redundancy in Information and Control Systems (REDUNDANCY), 2023 Next-generation wireless communication systems impose much stricter requirements for transmission rate, latency, and reliability. The peak data rate of 6G networks should be no less than 1 Tb/s, which is comparable to existing long-haul optical transport networks.

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