Spectral-Efficient MIMO-OFDM: Low-Complexity Solution based on Random Multiplexing
Jie Yang, Wanchen Hu, Yi Song +5
This paper presents a low-complexity precoded MIMO-OFDM system for achieving improved spectral efficiency (SE) via intentionally compressing information symbols among subcarriers.…
Capacity-Region-Achieving Sparse Regression Codes for MIMO Multiple-Access Channels
Hao Yan, Lei Liu, Yuhao Liu +2
This paper proposes a coding framework for capacity-region-achieving sparse regression (SR) codes over MIMO multiple-access channels (MIMO-MAC), where a single SR code is used for…
Distributed Memory Approximate Message Passing
Jun Lu, Lei Liu, Shunqi Huang +2
Approximate message passing (AMP) algorithms are iterative methods for signal recovery in noisy linear systems. In some scenarios, AMP algorithms need to operate within a distribut…
Overflow-Avoiding Memory AMP
Shunqi Huang, Lei Liu, Brian M. Kurkoski
Approximate Message Passing (AMP) type algorithms are widely used for signal recovery in high-dimensional noisy linear systems. Recently, a principle called Memory AMP (MAMP) was p…
