Over-Sampling Codebook-Based Hybrid Minimum Sum-Mean-Square-Error Precoding for Millimeter-Wave 3D-MIMO [PDF]
IEEE Wireless Communications Letters, 2018 Hybrid precoding design is challenging for millimeter-wave massive MIMO. Most prior hybrid precoding schemes are designed to maximize the sum spectral efficiency, while seldom investigating the bit-error-rate (BER). Therefore, this letter designs an over-

IEEE Access, 2021 Noise reduction is important for X-ray images because it can reduce radiation exposure to patients. X-ray image noise has a Poisson-Gaussian distribution, and recently, noise analysis and removal in multiscale transformations have been widely implemented.

Mean square cross error: performance analysis and applications in non-Gaussian signal processing
EURASIP Journal on Advances in Signal Processing, 2021 Most of the cost functions of adaptive filtering algorithms include the square error, which depends on the current error signal. When the additive noise is impulsive, we can expect that the square error will be very large.
