Patent ID: 7302013

Claim:
A method of recovering information from a received signal comprising: receiving a carrier signal modulated with the information; downconverting the carrier signal using a first fixed frequency oscillator to generate a downconverted signal; and processing, using a digital integrated circuit, the downconverted signal to generate an output signal representing the information, the processing including: sampling the downconverted signal using a second fixed frequency oscillator to generate a digital signal; regulating by a first digital feedback loop a frequency at which the output signal is generated, the first feedback loop carrying out processes of complex multiplication, variable interpolation, carrier recovery and digital frequency synthesizing to generate multiplying signals for the complex multiplication, and regulating, by a second digital feedback loop, a sampling time associated with the output signal, the second digital feedback loop carrying out processes of variable interpolation, and a symbol recovery, the processes of carrier recovery and symbol recovery both receiving signals resulting from variable interpolation.
