Realistic Channel Models Pre-training

no code implementations22 Jul 2019 Yourui Huangfu, Jian Wang, Chen Xu, Rong Li, Yiqun Ge, Xianbin Wang, Huazi Zhang, Jun Wang

In this paper, we propose a neural-network-based realistic channel model with both the similar accuracy as deterministic channel models and uniformity as stochastic channel models.

Reinforcement Learning for Nested Polar Code Construction

no code implementations16 Apr 2019 Lingchen Huang, Huazi Zhang, Rong Li, Yiqun Ge, Jun Wang

In this paper, we model nested polar code construction as a Markov decision process (MDP), and tackle it with advanced reinforcement learning (RL) techniques.

Learning to Flip Successive Cancellation Decoding of Polar Codes with LSTM Networks

no code implementations22 Feb 2019 Xianbin Wang, Huazi Zhang, Rong Li, Lingchen Huang, Shengchen Dai, Yourui Huangfu, Jun Wang

Specifically, before each SC decoding attempt, a long short-term memory (LSTM) network is exploited to either (i) locate the first error bit, or (ii) undo a previous `wrong' flip.

Predicting the Mumble of Wireless Channel with Sequence-to-Sequence Models

no code implementations14 Jan 2019 Yourui Huangfu, Jian Wang, Rong Li, Chen Xu, Xianbin Wang, Huazi Zhang, Jun Wang

Accurate prediction of fading channel in future is essential to realize adaptive transmission and other methods that can save power and provide gains.

Performance Evaluation of Channel Decoding With Deep Neural Networks

1 code implementation1 Nov 2017 Wei Lyu, Zhaoyang Zhang, Chunxu Jiao, Kangjian Qin, Huazi Zhang

With the demand of high data rate and low latency in fifth generation (5G), deep neural network decoder (NND) has become a promising candidate due to its capability of one-shot decoding and parallel computing.
