Abstract
One embodiment of the present invention provides a signal-recording system. During operation, the system receives a wideband multi-channel radio frequency (RF) signal, which includes a plurality of single-channel RF signals modulated at different carrier frequencies. The system down-converts the received wideband multi-channel RF signal to baseband, and records the down-converted signal.
