Summary
Summary
A study of modulated coding (MC), a technique for intersymbol interference (ISI) mitigation. It discusses MC when the ISI is known at both transmitter and receiver, and when only the receiver knows the ISI. It showcases polynomial antiquity resistant modulated coding, and provides an examination of transmitter-assisted ISI equalization.
