The Sampling Method for Optimal Precursors of ENSO Events
Bin Shi, Junjie Ma
El Niño-Southern Oscillation (ENSO) is one of the significant climate phenomena, which appears periodically in the tropic Pacific. The intermediate coupled ocean-atmosphere Zebiak-…
Asymptotic SEP Analysis and Optimization of Linear-Quantized Precoding in Massive MIMO Systems
Zheyu Wu, Junjie Ma, Ya-Feng Liu +1
A promising approach to deal with the high hardware cost and energy consumption of massive MIMO transmitters is to use low-resolution digital-to-analog converters (DACs) at each an…
Linear One-Bit Precoding in Massive MIMO: Asymptotic SEP Analysis and Optimization
Zheyu Wu, Junjie Ma, Ya-Feng Liu +1
This paper focuses on the analysis and optimization of a class of linear one-bit precoding schemes for a downlink massive MIMO system under Rayleigh fading channels. The considered…
Towards Designing Optimal Sensing Matrices for Generalized Linear Inverse Problems
Junjie Ma, Ji Xu, Arian Maleki
We consider an inverse problem , where is the signal of interest, is the sensing matrix, is a nonlinear fun…
Capacity Optimality of AMP in Coded Systems
Lei Liu, Chulong Liang, Junjie Ma +1
This paper studies a large random matrix system (LRMS) model involving an arbitrary signal distribution and forward error control (FEC) coding. We establish an area property based…
Compressed Coding, AMP Based Decoding and Analog Spatial Coupling
Shansuo Liang, Chulong Liang, Junjie Ma +1
This paper considers a compressed-coding scheme that combines compressed sensing with forward error control coding. Approximate message passing (AMP) is used to decode the message.…
