M-PSK Modulator Passband

Hi all, 've found in this tutorial [ http://www-rohan.sdsu.edu/doc/matlab/toolbox/commblks/usersguide/tutor218.html#69664 ] the M-PSK Modulator Passband block, but I can't found it on my Communication Blockset. Can anybody explain me why and maybe give me a solution for this? My Matlab version is the 7.5.0.

Thank you all!

The M-PSK Modulator Passband block in the Communications Blockset became obsolete in Release 14. The Release Notes suggest using the M-PSK Modulator Baseband block instead.

Can you use baseband modulation instead of passband modulation?

I'm sure I can use the baseband block, but I've to simulate a M-PSK passband system and I didn't found any model or tutorial that helps me..
