2GFSK-4GFSK demodulation in DSP based wireless receiver

The 2GFSK and 4GFSK modulation/demodulation technique has been used for years in wireless telecommunications like CT2, the DECT standard, digital cordless of SST and FH WLAN. This paper will explore the following areas of system design: 1) The basic signal model for FSK, GFSK and 4GFSK, 2) A coherent receiver with DSP based wireless architecture, 3) RF and DSP signal processing algorithms, with specific emphasis on low cost and low power multi-mode application in a DSP based wireless system and, 4) Detailed consideration of the design of a 2FSK, 4FSK DSP based wireless receiver for a pager system. The paper will explore a workable architecture and algorithm for a 2GFSK, 4GFSK DSP based wireless receiver
