Performance Analysis Of Bluetooth System Using Optimized Differential GFSK Demodulator N.M.SAI KRISHNA KUMAR M.Tech Student Scholar, DECS,

In this project, a simple demodulator for GFSK receivers is developed, which averages the phase based on the signal-to-noise ratio (SNR) maximizing criterion, and does not require knowledge of the exact modulation index. Compared to demodulators with similar complexity, such as the LDI, the presented receiver can achieve superior performance. In digital modulation, Gaussian frequency shift keying(GFSK) is one of the shifting technique. we are facing a challenging task in simple and high performance receivers for GFSK. In our project we develop an optimized differential GFSK demodulator and investigate the phase wrapping issue in its implementation. The Experimental results shows performance of bit error rate improvement in with conventional differential demodulators in both AWGN and flat fading channels. We also compare the simulation results with other exiting techniques like fading channels
