Receptor Digital para Medição de Balizas de Satélite

A prototype for a digital beacon receiver to be used in Earth-Satellite propagation experiments is presented.The HF signal is sampled at about 40Ms/s using a high speedADC, down converted and decimated by a signal processingchip. The output samples are processed by a DSP development kit that implements phase locked loop by software. The VCO is implemented by reprogramming the chip numerical oscillator (NCO). Pr...
