“…These values will be integrated to generate the phase, upon which the phase will pass through a phase-to-magnitude converter to generate the linear GMSK-modulated signal. But in direct phase decomposing method, a set of phase trajectories have already been predicted and stored in ROM to generate the modulated signal by passing through the phase-to-magnitude converter (Yunfu et al, 2007). Implementation of GMSK modulator has been carried out in ASIC platform (Bodas and Feher, 1996;Cardarilli et al, 2002;Tsai et al, 2000a;Haspeshlagh et al, 1990) by Digital Signal Processors (DSPs) Venkataraman and Collins, 2005;Souisi et al, 2008;Sebesta and Kasal, 2003) as well as FPGA boards (Gurubelli et al, 2009;Liu and Liu, 2008).…”

In Software Defined Radio (SDR), a single hardware structure can be reused to conform to different standards by simply changing some parameter. A low-power, high-speed, low-area parameter-controlled Common Baseband Modulator (CBM) architecture has been proposed in this paper. Using control parameters, the proposed CBM can be configured to support Gaussian Minimum Shift Keying (GMSK) as well as Frequency Modulation (FM) schemes. The design, which is fully pipelined, can operate at a maximum data rate of 276 Mbps. The proposed CBM consumes maximum dynamic power of 108.41 mW when running at 100 Mbps and using only 22.7 kilo equivalent gates.
