A preliminary performance evaluation of a linear frequency hopped modem
DJ Purle, A.R. Nix, Mark A Beach, Joe P. McGeehan · 2003
The benefits of using linear modulation methods for a frequency hopping (FH) transmission system in narrowband, i.e., voice cellular networks, are considered. In particular, the use of a 16-level modulation scheme derived from 16 QAM combined with FH is evaluated operating in a channel subject to noise and multipath fading, characteristic of the mobile environment.>
