    Abstract: A data transmitter is configured for transmitting multiple payload data streams in a frame format, wherein each frame comprises multiple rows, and each row comprises multiple bit slots. The data transmitter comprises: configuration storage circuitry, for storing frame format configuration data; an input, for receiving the multiple payload data streams; data multiplexing circuitry, for Combining the multiple payload data streams in accordance with the stored frame format configuration data to form a combined payload data stream; and redundancy code generator circuitry, for receiving the combined payload data stream, and generating check bit data therefrom. The data multiplexing circuitry is further configured for multiplexing the combined payload data stream and the check bit data into data for transmission in said frame format.

    Abstract: In a radio using a plurality of channels defined in a radio frequency (RF) spectrum, a rate of false packet detections may be calculated for each of the plurality of channels using a plurality of respective correlation thresholds. The rate of false packet detections for each channel may be compared to a range of acceptable rates of false packet detections. The same or different ranges of acceptable rates of false packet detections may be used for each channel or each channel plan. Different correlation thresholds may be adjusted based at least in part on the comparisons. For example, if a rate of false packet detections exceeds a range of acceptable rates of false packet detections, the correlation threshold may be raised, or the reverse. A packet may be detected on different channels based on different adjusted correlation thresholds.

    Abstract: Decoding of a first message is disclosed, wherein first and second messages are encoded by a code (represented by a state machine) to produce first and second code words, which are received over a communication channel. A plurality of differences (each corresponding to a hypothesized value of a part of the first message) between the first and second messages are hypothesized. An initial code word segment is selected having, as associated previous states, a plurality of initial states (each associated with a hypothesized difference and uniquely defined by the hypothesized value of the part of the first message). The first message is decoded by (for each code word segment, starting with the initial code word segment): combining the code word segment of the first code word with a transformed (based on the hypothesized difference of the initial state associated with the previous state of the state transition corresponding to a first message segment content) code word segment of the second code word to produce a combined code word segment, determining a decision metric associated with a probability that the combined code word segment corresponds to the first message segment content, and selecting (for the first message) the first message segment content or a second message segment content based on the decision metric. If the first message segment content is selected, the subsequent state of the state transition corresponding to the first message segment content is associated with the initial state associated with the previous state of the state transition.
