Abstract
A wireless communication system is provided that includes RF circuitry and signal processing circuitry. The signal processing circuitry includes a dedicated frequency burst (FB) search hardware circuit which exhibits relatively low noise in comparison with other digital processing circuitry, such as a DSP and MCU, within the system. The RF circuitry, dedicated FB search hardware circuit and the other digital processing circuitry can each be activated and inactivated. In one embodiment, when the RF circuitry and the dedicated FB search hardware are active, other digital processing circuitry remains inactive to avoid noise problems that could degrade reception and interfere with the FB search hardware locating the FB. Noise problems in the system are thus desirably reduced.
