Biphase Shift Keying (BPSK), Direct Sequence, Spread Spectrum Modem for Petite Amateur Navy Satellite (PANSAT).

摘要

The development of a biphase shift keying (BPSK), direct sequence, spread spectrum modem is conducted for the purpose of developing a prototype design to be implemented in Petite Amateur navy Satellite (PANSAT). The design discussion includes the hardware used in the functional realization of a working design. The design itself, encompasses selection of components, and demonstrates through circuit diagrams and waveforms produced that the preliminary operational characteristics of a spread spectrum BPSK modulation scheme for PANSAT have been achieved. Limited performance analysis is conducted through IF loop-back testing and analyzes the demodulator output waveforms providing the proof of concept for the design. The development of the final version operating at the specified radio frequency (RF) is not conducted....
