Hybrid Polar Encoding with Applications in Non-Coherent Channels
Mengfan Zheng
In coding theory, an error-correcting code can be encoded either systematically or non-systematically. In a systematic encode, the input data is embedded in the encoded output. Con…
PAC Codes for Source and Joint Source-Channel Coding
Mengfan Zheng, Cong Ling
Polarization-adjusted convolutional (PAC) codes, as a concatenated coding scheme based on polar codes, is able to approach the finite-length bound of binary-input AWGN channel at s…
Joint Device Detection, Channel Estimation, and Data Decoding with Collision Resolution for MIMO Massive Unsourced Random Access
Tianya Li, Yongpeng Wu, Mengfan Zheng +5
In this paper, we investigate a joint device activity detection (DAD), channel estimation (CE), and data decoding (DD) algorithm for multiple-input multiple-output (MIMO) massive u…
SPARC-LDPC Coding for MIMO Massive Unsourced Random Access
Tianya Li, Yongpeng Wu, Mengfan Zheng +2
A joint sparse-regression-code (SPARC) and low-density-parity-check (LDPC) coding scheme for multiple-input multiple-output (MIMO) massive unsourced random access (URA) is proposed…
Large Intelligent Surface Aided Physical Layer Security Transmission
Biqian Feng, Yongpeng Wu, Mengfan Zheng +3

On the Polarization of Rényi Entropy
Mengfan Zheng, Ling Liu, Cong Ling
Existing polarization theories have mostly been concerned with Shannon's information measures, such as Shannon entropy and mutual information, and some related measures such as the…

Mengfan Zheng, Wen Chen, Cong Ling
In this paper, we propose a low-complexity, secrecy capacity achieving polar coding scheme for the cognitive interference channel with confidential messages (CICC) under the strong…
Polar Coding for Block Fading Channels
Mengfan Zheng, Meixia Tao, Wen Chen +1
In this paper, we consider the problem of polar coding for block fading channels, with emphasis on those with instantaneous channel state information (CSI) at neither the transmitt…
Secure Polar Coding for the Two-Way Wiretap Channel
Mengfan Zheng, Meixia Tao, Wen Chen +1
We consider the problem of polar coding for secure communications over the two-way wiretap channel, where two legitimate users communicate with each other simultaneously while a pa…
Polar Coding Strategies for the Interference Channel with Partially-Joint Decoding
Mengfan Zheng, Cong Ling, Wen Chen +1
Existing polar coding schemes for the two-user interference channel follow the original idea of Han and Kobayashi, in which component messages are encoded independently and then ma…
Polar Coding for Secure Transmission in MISO Fading Wiretap Channels
