Abstract

The modulation system of Gaussian filtered Minimum Shift Keying (GMSK) is a narrow band and constant envelope format that is acceptable for bandwidth, power restricted environment of radio communication. The modulation technique encounters extensive approval from the cellular network market. Nonetheless, the present GMSK modulation scheme is majorly held back due to its two critical shortcomings, the necessity at the receiver section to shape the GMSK's symbol pulses for ISI and the absence of amended GMSK model including the bandwidth efficiency to improvise the link quality. At the moment, rare progressive research studies are being conducted in favor of hardware implementation of GMSK that can satisfactorily be applied to any GSM or AIS application. A standardized algorithm or framework that can guarantee high resiliency is yet to be introduced. Therefore, the paper gives a comprehensive outlook in the direction of understanding the drawbacks that are posed for the implementation of GMSK.
