Analysis and Compensation of Tx and Rx IQ Imbalances in AFDM System
Hongjun Liu, Liaoyuan Zeng, Junhao Tian +4
Affine frequency division multiplexing (AFDM) is a recently proposed multicarrier waveform whose bit error rate (BER) performance in doubly selective channels is comparable to that…
Analysis and algorithms for some compressed sensing models based on L1/L2 minimization
Liaoyuan Zeng, Peiran Yu, Ting Kei Pong
Recently, in a series of papers [32,38,39,41], the ratio of and norms was proposed as a sparsity inducing function for noiseless compressed sensing. In this paper…
A difference-of-convex approach for split feasibility with applications to matrix factorizations and outlier detection
Chen Chen, Ting Kei Pong, Lulin Tan +1
The split feasibility problem is to find an element in the intersection of a closed set and the linear preimage of another closed set , assuming the projections onto and…
An AI Based Super Nodes Selection Algorithm in BlockChain Networks
Jianwen Chen, Kai Duan, Rumin Zhang +2
In blockchain systems, especially cryptographic currencies such as Bitcoin, the double-spending and Byzantine-general-like problem are solved by reaching consensus protocols among…
