Dear all I can't find the related files to FSK Modulation (NRZ) in NS2.34. How can I find (or probably implement) this propagation model. i found bpsk in Modulation.h but i can't find fsk. I am looking forward to receiving your comments & related codes for NS2. Thanks in advance, Kind regards, Ali Balador **************************** Homepage: WWW.BALADOR.ORG ***************************
