Abstract: Embodiments of methods and systems for supporting coexistence of multiple technologies in a Power Line Communication (PLC) network are disclosed. A long coexistence preamble sequence may be transmitted by a device that has been forced to back off the PLC channel multiple times. The long coexistence sequence provides a way for the device to request channel access from devices on the channel using other technology. The device may transmit a data packet after transmitting the long coexistence preamble sequence. A network duty cycle time may also be defined as a maximum allowed duration for nodes of the same network to access the channel. When the network duty cycle time occurs, all nodes will back off the channel for a duty cycle extended inter frame space before transmitting again. The long coexistence preamble sequence and the network duty cycle time may be used together.

Abstract: An example method includes: receiving a test phrase; comparing feature vectors of the test phrase to contents of a first database to generate a first score; comparing the feature vectors of the test phrase to contents of a second database to generate a second score; comparing feature vectors of the contents of the second database to the contents of the first database to generate a third score; comparing the feature vectors of the contents of the second database to a model of the test phrase to generate a fourth score; determining a first difference score based on a difference between the first and second scores; determining a second difference score based on a difference between the third and fourth scores; and generating a difference confidence score based on a lesser of the first and second difference scores.

Abstract: An orthogonal frequency division multiplexing (OFDM) receiver includes detection logic, offset generation logic, tone erasure logic, and correction generation logic. The detection logic is configured to detect a signal containing a block of samples that includes a narrowband interferer from a communication channel. The offset generation logic is configured to align a frequency of the narrowband interferer to a center of a subcarrier frequency of the communication channel to produce an offset signal thereby introducing inter-carrier interference (ICI). The tone erasure logic is configured to remove the subcarrier frequency from the offset signal to produce an interferer erased offset signal. The correction generation logic is configured to remove the ICI to produce an interferer erased signal.

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: A vehicle navigation system includes a GNSS position engine (GPE) that uses GNSS satellite measurements to compute a first position and velocity of a vehicle and a first quality metric associated with the position and velocity. The system also includes a dead reckoning engine (DRE) that operates parallel with the GPE that computes a second position and velocity and a second quality metric associated with the dead reckoning. The GPE is configured to use the second position and velocity to detect a set of outliers in an incoming GNSS measurement; use the second position and velocity as an initial estimate of its position and velocity for a particular time instant, which is then refined by GNSS measurements received at that particular time instant; and to replace the first position and velocity with the second position and velocity.
