Broadband digitizer used for channel assessment

Abstract:

Within a radio, a broadband digitizer is configured for channel assessment. In an example, a radio band is digitized to form a data stream. The data stream is channelized to form first and second in-phase in-quadrature (I/Q) sample streams. The first and second I/Q sample streams are provided to first and second channel assessors, respectively. Additionally, the first and second I/Q sample streams are bifurcated, to thereby provide the same first and second I/Q streams to first and second channel decoders, respectively. Accordingly, same portions of the first and second I/Q sample streams are presented to the first and second channel assessors and the first and second decoders, respectively, at the same time. Based at least in part on the channel assessments made by the channel assessors, a channel plan with less radio frequency noise may be selected.
