About This Site

I started this site to share notes from topics I was learning. It now also serves as an academic homepage while preserving older writing in information theory, communications, mathematics, and related areas. Some older notes are in Chinese and may reflect an earlier stage of my studies.

Posts use the following status labels:

Status Meaning
