GMSK represents the state of each 2-data-bit symbol as either a 45°-, 135°-, 225°- or 315°-phase shift as does MSK modulation. But for GMSK, a Gaussian filter smoothes the phase transitions ...

GSM systems operate using a Gaussian minimum-shift keying (GMSK) modulation scheme that has a constant envelope. 2 In order to provide a more bandwidth-efficient signal for high data rate applications ...

The big problem is that EDGE does not use the constant envelope GMSK (Gaussian filtered minimum shift keying) modulation that is used in GSM/GPRS. The 3π/8-8PSK modulation has both a phase and ...

In addition to handling the receive downconversion, the RF6001 includes all of the transmit functions. Specifically, on the transmit front, the IC offers both digital and analog I/Q interfaces, a ...

Digital modulations include FSK, GFSK, MSK, GMSK, HMSK, 3FSK, 4FSK, PSK, ASK, and OOK. Built in NRZ patterns include square wave, 7, 9, 11 & 15-bit PRBS. Digital modulation capabilities also include ...
