Noncoherent SIMO detection by expectation propagation
2017 IEEE International Conference on Communications (ICC), 2017An algorithm based on expectation propagation (EP) is proposed for noncoherent symbol detection in large-scale SIMO systems. It is verified through simulation that in terms of symbol error rate (SER), the proposed detector outperforms the pilotbased coherent MMSE detector for blocks as small as two symbols. This makes the proposed detector suitable for

Decentralized Signal Detection via Expectation Propagation Algorithm for Uplink Massive MIMO Systems
IEEE Transactions on Vehicular Technology, 2020The existing centralized antenna array architecture and the corresponding centralized baseband processing based signal detection algorithms incur huge burden on the raw baseband data rates and chip input/output bandwidth for massive multiple-input ...

A Low-Complexity Massive MIMO Detection Based on Approximate Expectation Propagation
IEEE Transactions on Vehicular Technology, 2019Among various massive multiple-input multiple-output (MIMO) signal detection schemes, expectation propagation (EP) achieves superior performance in high-dimensional systems with high-order modulations and flexible antenna configurations.

Back propagation with expected source values
Neural Networks, 1991Abstract The back propagation learning rule converges significantly faster if expected values of source units are used for updating weights. The expected value of a unit can be approximated as the sum of the output of the unit and its error term. Results from numerous simulations demonstrate the comparative advantage of the new rule.

Block expectation propagation equalization for ISI channels
2015 23rd European Signal Processing Conference (EUSIPCO), 2015Actual communications systems use high-order modulations and channels with memory. However, as the memory of the channels and the order of the constellations grow, optimal equalization such as BCJR algorithm is computationally intractable, as their complexity increases exponentially with the number of taps and size of modulation.
