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.…
An Orthogonal Approximate Message Passing Framework for Multiuser Communications
Burak Çakmak, Hao Yan, Alexander Fengler +2
We solve the open problem of constructing a Bayes-optimal iterative signal recovery algorithm for linear-Gaussian \emph{multiuser} communication systems with random precoding at th…
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…
Sparse Regression LDPC Codes for the Block-Fading Non-Coherent SIMO Channel
Alexander Fengler, Burak Çakmak, Giuseppe Caire
Sparse regression codes (SPARCs) are a class of codes that encode information through the superposition of columns of a randomised coding matrix. The combination with an outer non-…
Multi-Source Approximate Message Passing with Random Semi-Unitary Dictionaries
Burak Çakmak, Giuseppe Caire
Motivated by the recent interest in approximate message passing (AMP) for matrix-valued linear observations with superposition of \emph{multiple statistically asymmetric signal sou…
