                         with fully digital architecture, aimed at high speed (10 Mbps) 
                         space telemetry applications in which the absolute Doppler offset 
                         may reach up to 200 kHz. All functional modules that compose the 
                         demodulator are described through block diagrams and mathematical 
                         equations. The calculations for the determination of several 
                         design parameters are presented. The carrier phase and the symbol 
                         timing recovery modules are distinct from those found in the 
                         literature for this application and, therefore, original 
                         mathematical analysis for the project of such modules are 
                         performed. The performance of the proposed GMSK demodulator is 
                         evaluated via computational simulation. Besides the bit error rate 
                         under several operating conditions, the variance of the estimated 
                         parameters by the symbol and carrier synchronizers are measured 
                         and compared with theoretical bounds. The main results from 
                         computational simulations are presented and demonstrate remarkable 
                         performance of the designed demodulator.",
