Abstract: One embodiment of the present invention provides a system for dynamic, on-demand, cross-channel bandwidth provisioning in a wireless communication system. During operation, the system determines, by a scheduler, bandwidth resources that are available in the wireless communication system. The available bandwidth resources comprise a plurality of scattered spectrum pieces. The system defines one or more logical channels that encompass the scattered spectrum pieces, aggregates multiple logical channels in response to determining that spectrum pieces encompassed by a single logical channel do not meet traffic need, and provisions a user or a service using spectrum pieces located within the aggregated multiple logical channels, thereby facilitating on-demand, cross-channel bandwidth provisioning.

Abstract: One embodiment of the present invention provides a signal-recording system. During operation, the system receives a plurality of radio frequency (RF) signals, separates the RF signals to obtain a first group of RF signals in a first RF band and a second group of RF signals in a second RF band, and simultaneously down-converts the first group of RF signals to a first group of low intermediate-frequency (low-IF) signals in a first IF band and the second group of RF signals to a second group of low-IF signals in a second IF band. The system further converts the first group of low-IF signals and the second group of low-IF signals to the digital domain, and simultaneously processes all of the converted low-IF signals.
