Abstract: A method of communicating a packet between a first node and a second node, the packet comprising a data payload and a portion of information preceding the data payload. The method comprises: (i) first, identifying a quality of a channel between the first node and the second node; (ii) second, in response to the quality of the channel, selecting a manner of communication of the information preceding the data payload; (iii) third, encoding the selected manner of communication in the portion of information preceding data payload; and (iv) fourth, transmitting the packet from the first node to the second node.

Abstract: A method of encoding a first bit and a second bit for transmission on a transmission band is provided. The method includes receiving a bit stream that includes the first and second bits, mapping the first bit into a first symbol, mapping the second bit into a second symbol, differentially encoding at least the first symbol and the second symbol, and causing the first and second symbols to be transmitted on a transmission band as part of a symbol stream.

Abstract: Disclosed examples include heart rate monitor systems and methods to estimate a patient heart rate or rate of another pulsed signal, in which rate hypotheses or states, are identified for a current time window according to digital sample values of the pulsed signal for a current sample time window, and a rate change value is computed for potential rate transitions between states of the current and previous time windows. Transition pair branch metric values are computed as a function of the rate change value and a frequency domain amplitude of the corresponding rate hypothesis for the current time window, and the pulsed signal rate estimate is determined according to a maximum path metric computed according to the branch metric value and a corresponding path metric value for the previous time window.

Abstract: In described examples, a method for detecting voice activity includes: receiving a first input signal containing noise; sampling the first input signal to form noise samples; determining a first value corresponding to the noise samples; subsequently receiving a second input signal; sampling the second input signal to form second signal samples; determining a second value corresponding to the second signal samples; forming a ratio of the second value to the first value; comparing the ratio to a predetermined threshold value; and responsive to the comparing, indicating whether voice activity is detected in the second input signal.

Abstract: Embodiments include methods of powerline communications using a preamble with band extension is provided. A method may include receiving a packet data unit PDU. Bit-level repetition is applied to at least a portion of the PDU to create a repeated portion. Interleaving is performed per a subchannel. Pilot tones are inserted in the interleaved portion. Each data tone is modulated with respect to a nearest one of the inserted pilot tones. The PDU is transmitted over a power line.

Abstract: Embodiments of the invention provide multiple cyclic prefix lengths for either both the data-payload and frame control header or only the data payload. Frame control header (FCH) and data symbols have an associated cyclic prefix. A table is transmitted in the FCH symbols, which includes a cyclic prefix field to identify the cyclic prefix length used in the data payload. A receiver may know the cyclic prefix length used in the FCH symbols in one embodiment. In other embodiments, the receiver does not know the FCH cyclic prefix length and, therefore, attempts to decode the FCH symbols using different possible cyclic prefix lengths until the FCH symbols are successfully decoded.

Abstract: In a powerline communications (PLC) network having a first node and at least a second node on a PLC channel utilizing a band including a plurality of tones, based on at least one channel quality indicator (CQI), the first node allocates for a tone map response payload only a single (1) power control bit for each of a plurality of subbands having two or more tones. The power control bit indicates a first power state or a second power state. The first node transmits a frame including the tone map response payload to the second node. The second node transmits a frame having boosted signal power for the tones in the subbands which have the first power state compared to a lower signal power for the tones in the subbands which have the second power state.
