The dhparam command has mostly been used with Apache, as far as I know; ssh provides its own commands as part of ssh-keygen, which are described in the man page you just mentioned.
However, the paper authors say
"If you use SSH, you should upgrade both your server and client installations to the most recent version of OpenSSH, which prefers Elliptic-Curve Diffie-Hellman Key Exchange."
That might ultimately be a simpler and safer course unless you have to deal with old clients that you don't have the ability to upgrade.
