Lower-Error and Area-Efficient Complex Divider Design using Logarithmic Number Systems (LNS)
Tso‐Bing Juang, Chun-Chi Fan, Guan-Zhong Lin · 2023
In this paper, new complex dividers based on logarithmic number systems (LNS) proposed. Using LNS representations, the hardware cost for dividing two complex numbers can be greatly saved in addition to reduced delay. Synthesis results and error analysis demonstrate that our proposed LNS-based complex dividers could achieve 98.05% ADP (Area Delay Product) reductions with lower errors, which are useful for many high-speed applications in digital signal processing such as complex SVD, earthfault distance protection, and astronomy.
