Sleep, Sense or Transmit: Energy-Age Tradeoff for Status Update with Two-Thresholds Optimal Policy

Jie Gong, Jianhang Zhu, Xiang Chen +1

Age-of-Information (AoI), or simply age, which measures the data freshness, is essential for real-time Internet-of-Things (IoT) applications. On the other hand, energy saving is ur…

Twisted-Pair Superposition Transmission

Suihua Cai, Xiao Ma

We propose in this paper a new coding scheme called twisted-pair superposition transmission (TPST). The encoding is to "mix together" a pair of basic codes by superposition, while…

Transmitting Extra Bits by Rotating Signal Constellations

Jiachen Sun, Hao Liu, Xiao Ma

In this letter, we propose a novel LDPC coding scheme to transmit extra bits aided by rotated signal constellations without any additional cost in transmission power or bandwidth.…

Binary Representaion for Non-binary LDPC Code with Decoder Design

Yang Yu, Wen Chen, Jun Li +2

The equivalent binary parity check matrices for the binary images of the cycle-free non-binary LDPC codes have numerous bit-level cycles. In this paper, we show how to transform th…

Analysis on Computation-Intensive Status Update in Mobile Edge Computing

Qiaobin Kuang, Jie Gong, Xiang Chen +1

In status update scenarios, the freshness of information is measured in terms of age-of-information (AoI), which essentially reflects the timeliness for real-time applications to t…

Systematic Convolutional Low Density Generator Matrix Code

Suihua Cai, Wenchao Lin, Xinyuanmeng Yao +2

In this paper, we propose a systematic low density generator matrix (LDGM) code ensemble, which is defined by the Bernoulli process. We prove that, under maximum likelihood (ML) de…
