Finite-Precision Conjugate Gradient Method for Massive MIMO Detection
Yiming Fang, Li Chen, Changsheng You +2
The implementation of the conjugate gradient (CG) method for massive MIMO detection is computationally challenging, especially for a large number of users and correlated channels.…
Revisiting MUSIC: A Finite-Precision Perspective
Yiming Fang, Li Chen, Ang Chen +1
The high computational complexity of the multiple signal classification (MUSIC) algorithm is mainly caused by the subspace decomposition and spectrum search, especially for frequen…
Mixed-Precision Quantization: Make the Best Use of Bits Where They Matter Most
Yiming Fang, Li Chen, Yunfei Chen +2
Mixed-precision quantization offers superior performance to fixed-precision quantization. It has been widely used in signal processing, communication systems, and machine learning.…
Statistical Rounding Error Analysis for Random Matrix Computations
Yiming Fang, Li Chen
The conventional rounding error analysis provides worst-case bounds with an associated failure probability and ignores the statistical property of the rounding errors. In this pape…
