A examine of modulated coding (MC), a strategy for intersymbol interference (ISI) mitigation. It discusses MC while the ISI is understood at either transmitter and receiver, and whilst basically the receiver understands the ISI. It showcases polynomial antiquity resistant modulated coding, and offers an exam of transmitter-assisted ISI equalization.
