Abstract
A wide band receiver to select and demodulate an input signal with single scan spectrum sensing by performing filtering on the input signal in digital domain to achieve improved selectivity and sensitivity is provided. The input signal includes one or more narrowband radio frequency (RF) signals. The wide band receiver includes a wide band tuner that down converts the one or more narrowband RF signals to one or more IF signals. An analog to digital converter (ADC) converts the one or more IF signals to one or more digital signals. A filter rejects out-of-band signals from the one or more digital signals to achieve the improved selectivity. A numeric controlled oscillator (NCO) selects at least one narrowband digital signal from the digital signals based on a phase value obtained from a spectrum selection control unit. A demodulator demodulates the narrowband digital signal to obtain a demodulated digital signal.
