摘要
A receiver is provided for use in an environment in which both frequency-hopping and direct-sequence spread spectrum radio frequency (RF) signals are present. The receiver includes a receive section adapted to receive and downconvert RF input signals. A detector is coupled to the receive section, and has a plurality of parallel filter stages with each tuned for a distinct frequency band. A discriminator compares the RF energy level passing through each of the filter stages to determine whether the RF input signals are frequency-hopping or direct-sequence spread spectrum signals. A controller is adapted to control the receive section in response to the discriminator.
