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.…
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…
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.…
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…
