摘要
A frequency downconversion receiver is provided that does not require predictive filtering for signal acquisition and synchronization. A sync block modulates a voltage-controlled oscillator (VCO) with twice the frequency of the incoming modulated receive signal. From this, the bit position of the incoming data can be determined. The value of the incoming data can be determined from whether the VCO output and the demodulator output have consecutive predetermined values.
