Simulation and performance analysis of Cellular Digital Packet Data
… Using idle time between voice traffic, CDPD uses Gaussian Minimum Shift Keying (GMSK) to send bursts of Reed-Solomon encoded information while channel hopping to avoid interfering with voice transmissions. This thesis assesses the performance of CDPD for different channel environments through …

Error and erasure decoding for a CDPD system
… hopping technique. The CDPD system employs Gaussian minimum shift keying (GMSK) as a modulation scheme and a Reed-Solomon code for error control to transmit high-quality data in the mobile and wireless environment. Most current CDPD receivers use errors only decoding of the Reed-Solomon …

Performance of GMSK and 7/4-DQPSK Modulations in Land Mobile Radio Channels
… systems will find increasing application. Gaussian Minimum Shift Keying (GMSK) and 7r/4-Differential Quadrature Phase Shift Keying (7r/ 4-DQPSK) have been identified as the modulation methods for the European and the North American digital cellular systems respectively. The communication …

Robust GMSK Demodulation Using Demodulator Diversity and BER Estimation
This research investigates robust demodulation of Gaussian Minimum Shift Keying (GMSK) signals, using demodulator diversity and real-time bit-error-rate (BER) estimation. GMSK is particularly important because of its use in promi- nent wireless standards around the world (GSM, DECT, CDPD, DCS1800, …
