Abstract: Systems and methods are provided for a radar processing chain for frequency-modulated continuous wave radar systems. A transmitter transmits a plurality of chirps, each comprising an electromagnetic radiation signal, at a region of interest. A receiver front-end receives reflected electromagnetic radiation for each chirp and generates a time series of beat-signal samples for each chirp at each antenna of a plurality of antennas. A signal processor detects objects within the region of interest by providing a frequency domain representation of each time series of beat-signal samples as sample values for a set of range bins representing respective distances from the receiver, correcting the sample values for each of the set of range bins to provide a set of clutter corrected samples for each range bin, and determining an angular spectrum for each of a subset of the set of range bins from the clutter corrected samples.

Abstract: A method for performing code block segmentation for wireless transmission using concatenated forward error correction encoding includes receiving a transport block of data for transmission having a transport block size, along with one or more parameters that define a target code rate. A number N of inner code blocks needed to transmit the transport block is determined. A number M-outer code blocks may be calculated based on the number of inner code blocks and on encoding parameters for the outer code blocks. The transport block may then be segmented and encoded according to the calculated encoding parameters.

Abstract: A symbol modulation system applicable to a body area network is disclosed herein. The symbol modulation system includes a symbol mapper. The symbol mapper is configured to determine a time within a predetermined symbol transmission interval at which a transmission representative of the symbol will occur. The time is determined based on a value of a symbol and a value of a time-hopping sequence. The time is selected from a plurality of symbol value based time slots, and a plurality of time-hopping sequence sub-time-slots within each symbol value based time slot. The symbol mapper is configured to generate a single guard interval within the symbol transmission interval. The single guard interval is positioned to terminate the symbol transmission interval.
