# Is there some literature to understand finite state ISI channel?

I am trying to understand channels with memory, where the state of the channel gives the past input information. I want to delve further into capacity for channels with ISI. I came across a presentation given here, on the $5^{th}$ page of it I found a Markov and dicode representation like this: .

I want to know if there is some primarily literature that concerns itself with understanding this channel, and specifically how to read this binary channel with ISI, and also with dicode channels. Any help will be great

• I would start with Proakis, "Digital Communications". It devotes one chapter to ISI channels, and it's a classic reference. – MBaz May 30 '18 at 13:39
