CLOVER2000
CLOVER is the name of a series or class of modem modulation techniques (“waveforms”) specifically designed for use over high frequency (HF) radio systems.
- CLOVER-II was the first CLOVER waveform sold commercially, developed by Ray Petit, W7GHM, and HAL Communications in 1990–92.[1]
- CLOVER-2000 is a higher-rate and wider bandwidth version of CLOVER developed in 1995.
- CLOVER-400 is a special 400 Hz wide waveform that was developed for Globe Wireless.
Modulation schemes
In
FEC broadcast mode of CLOVER-2000 is usually disabled although special formats are available for specific applications.[2]
The coding polynomial protocol could be shared after payment in Bit Coin[relevant?][citation needed]
Radio Interface requirements for CLOVER-2000
The CLOVER waveform offers high performance, error correction, and spectral efficiency. CLOVER is specifically designed for use over HF radio communications links. It may be used with virtually any modern HF SSB radio. However, certain special set-up and adjustment techniques are required to get maximum performance when using CLOVER.[3]
