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.

“…The only variation is, instead of the shape of the half-sine pulse the inputs bits form the shape of the Gaussian bell curve. The realization of such shapers is carried using different digital or analog circuits of PCM LUTs [1][2][3][4][5][6][7].The present wireless digital communication systems use different types of modulation techniques to achieve high performance with efficient usage of available spectrum efficiency. The MSK provides the constant envelope signals for power amplification which reduces the problems caused by non-linear distortion, and MSK encodes each bit is like a half sinusoidal.…”

“…The American /European countries use GMSK modulation schemes in cellular phones as per GSM standards. The GMSK supports non-linear modulation, which is used for easy implementation on hardware [3][4][5]. If the Radio signal frequency increases in mobile communication and it is difficult to use by conventional technology like DSP, Microcontroller and Microprocessor in the real-time conditions due to its computational complexities.…”

The Gaussian Minimum Shift Keying (GMSK) modulation is a digital modulation scheme using frequency shift keying with no phase discontinuities, and it provides higher spectral efficiency in radio communication systems. In this article, the cost-effective hardware architecture of the GMSK system is designed using pipelined CORDIC and optimized CORDIC models. The GMSK systems mainly consist of the NRZ encoder, Integrator, Gaussian filter followed by FM Modulator using CORDIC models and Digital Frequency Synthesizer (DFS) for IQ Modulation in transmitter section along with channel, the receiver section has FM demodulator, followed by Differentiator and NRZ decoder. TheCORDIC algorithms play a crucial role in GMSK systems for IQ generation and improve the system performance on a single chip. Both the pipelined CORDIC and optimized CORDIC models are designed for 6-stages. The optimized CORDIC model is designed using quadrature mapping method along with pipeline structure. The GMSK systems are implemented on Artix-7 FPGA with FPGA prototyping. The Performance analysis is represented in terms of hardware constraints like area, time and power. These results show that the optimized CORDIC based GMSK system is a better option than the pipelined CORDIC based GMSK systems for real-time scenarios.

The Gaussian minimum shift keying (GMSK) is one of the best suited digital modulation schemes in the global system for mobile communication (GSM) because of its constant envelop and spectral efficiency characteristics. Most of the conventional GMSK approaches failed to balance the digital modulation with efficient usage of spectrum. In this article, the hardware architecture of the optimized CORDIC-based GMSK system is designed, which includes GMSK Modulation with the channel and GMSK Demodulation. The modulation consists of non-return zero (NRZ) encoder, an integrator followed by Gaussian filtering and frequency modulation (FM). The GMSK demodulation consists of FM demodulator, followed by differentiation and NRZ decoder. The FM Modulation and demodulation use the optimized CORDIC model for an In-phase (I) and quadrature (Q) phase generation. The optimized CORDIC is designed by using quadrant mapping and pipelined structure to improve the hardware and computational complexity in GMSK systems. The GMSK system is designed on the Xilinx platform and implemented on Artix-7 and Spartan-3EFPGA. The hardware constraints like area, power, and timing utilization are summarized. The comparison of the optimized CORDIC model with similar CORDIC approaches is tabulated with improvements.
