CLOVER 2500
CLOVER-I | CLOVER-II | CLOVER 2000 | CLOVER 2500
CLOVER 2500 is a new upgrade to CLOVER 2000, adding 25% more speed to the CLOVER system. CLOVER-2500 was released in 2011 by HAL Communications.
CLOVER-2500 uses 8 312.5 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). wide tone-pulse subcarriers that are each offset from the base tone by 1.6ms, so that every 12.8ms all eight tone pulses transmit their cycle. CLOVER-2500 uses Phase (PSKPhase-Shift Keying) or Phase-Amplitude (Circular QAMQuadrature Amplitude Modulation) shift keying modulation. CLOVER-2500 occupies 2.5 kHzKiloHertz (kHz) 10^3 Hz of bandwidth in contrast to CLOVER-2000's 2000 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). of bandwidth. The symbol rate for CLOVER-2500 is increased to 78.125 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. for all modes, 25% faster than CLOVER-2000's 62.5 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second..
