             abstract = "One challenge in satellite development concerns to the performance 
                         of the communication link and the adopted technology. In this 
                         paper, we present the design of a fully-digital BPSK demodulator 
                         that is part of a satellite on-board telemetry, tracking and 
                         command transponder. The calculations for the determination of 
                         several project parameters, the block diagrams and equations of 
                         all the functional modules compounding the demodulator are 
                         described. The architecture of the demodulator and of some 
                         functional modules differs from similar solutions found in the 
                         literature. The performance of the proposed demodulator was 
                         evaluated by mathematical analysis and computational simulation. 
                         Some of such analyzes are original as well as some statistical 
                         characterizations of the signals that were done via simulation. In 
                         addition, we evaluated the system bit error rate, under various 
                         operating conditions, and the variance of the parameters estimated 
                         by the carrier and the symbol synchronizers. The results 
                         demonstrated that the proposed solution complies with the 
                         requirements of the project. In the worst case of operation, the 
                         system performance is only 0.3 dB below the theoretical limit, for 
                         the condition when the bit error rate is equal to 10^-5.",
