Abstract: Methods and systems for decoding monitored communication signals using previously identified side information. Information, which is used for decoding a given frame and is provided to the decoder not via the main communication channel between a base station and a mobile station, is referred to herein as “side information.” The side information can also be viewed as extrinsic information that was derived during previous decoding operations. The monitoring system holds, for certain frames, a-priori information of one or more data values that are expected in these frames. Decoding using this a-priori information enables an Error Correcting Code decoder to successfully decode such frames, which would otherwise fail to decode.

Abstract: Methods and systems for passive monitoring and analysis of large numbers of cellular communication channels. The processing functions of a monitoring system are split between a front-end processor and a host that communicate over an interface. The front-end processor may comprise a signal-processing board installed in the computer, and the interface comprises a Peripheral Component Interconnect Express (PCIe) bus. A Radio Frequency (RF) receiver receives and down-coverts one or more RF bands of interest, which comprise a large number of communication channels. The front-end processor digitizes the received signals and produces a plurality of single-channel digital signals. In order to avoid high data rates, the front-end processor generates and sends to the host multi-channel digital signals instead of single-channel digital signals for processing. Each multi-channel digital signal comprises a respective set of communication channels (e.g., four channels), which are distributed over frequency.
