There are only two relevant lines from your enormous blocks of code (that you didn't format yourself):
%initial post:
h_16qam=qammod('M',16,'inputtype','bit');
%second post:
h_16qam=modem.qammod('M',16,'inputtype','bit');
Did you read the documentation? It explains the syntax that you can use for that function. I can't find explicit documentation for modem.qammod, but for the qammod function you can find the syntax in the doc pages I linked. Judging by what I could find, I suspect the correct syntax in your case should be this:
%remove these two lines:
h_16qam=modem.qammod('M',16,'inputtype','bit');
y_16qam=modulate(h_16qam,input);
%replace by:
y_16qam=qammod(input,16,'inputtype','bit');
I'm not entire sure if you need to change something about the input variable.

As stated in the release notes for Communcation Toolbox the modem.qammod function has been removed. Replace it with a call to qammod.
If you need this code to run in both release R2012a and release R2019a, you can wrap the modem.qammod call in a try / catch block or you can detect whether you're using a release that includes the modem package with verLessThan.

@Stephen, I searched the RN as well, but was unable to find this. Now I found out that I can't rely on the search tool, but I should check each product separately (the MATLAB search option apparently only being for the base product). Thank you for revealing this to me.

Rik: Searching the Release Notes for "qammod" found three hits for me, the first of which is the Communications Toolbox RNs. If I change that to "modem.qammod" the Communications Toolbox notes are the only hit.
krishna kotha: If you want to run this code in R2019a, replace modem.qammod calls with calls to qammod. I don't know offhand if the syntax for the two is the same or if you'll need to adjust how you call the function slightly.

Character vector inputs have been removed.
Instead, use syms to declare variables and replace inputs
such as solve('2*x == 1','x') with solve(2*x == 1,x).
So let's do that. Since the R2012a version of solve also supports sym inputs, we don't need to worry about any incompatiblity.
%don't use globals
%use other methods of sharing data between callback (like e.g. guidata)
syms P_av
P_av_result=solve(log(P_av)+(0.5/P_av)+log(p)==0,P_av);
%don't use ans, just store the result
