Abstract: Methods and systems are disclosed to adjust communication links within wireless networks based upon composite link quality indicators (LQIs). Packet communications are received by a network node through a communication link from a separate network node within a wireless network. The network node can also be configured to transmit packet communications from the network node through the communication link to the separate network node. The network node generates composite LQI measurements for the received packet communications, and the composite LQI measurements are based upon signal strength measurements for the received packet communications and also based upon signal quality measurements for the received packet communications. The network node then adjusts the communication link based upon the composite LQI measurements.

Abstract: A communication device performs information communication through a communication line based on communication data specified by a CAN protocol. A communication necessity determination unit determines whether or not the information communication through the communication line is necessary based on external information obtained from an external device. When the information communication is necessary and a communication error is detected, a communication control unit stops the information communication during a fixed period and restarts the information communication after the fixed period elapses. When the information communication is unnecessary, the communication control unit stops transmitting communication data until a predetermined transmission restarting condition is satisfied.

Abstract: A Power-Line Communication (PLC) receiver has a filter, a time domain processor, a frequency-domain processor, and a forward-error-correction decoder. A narrow-band frequency detector attached to the frequency-domain processor examines the frequency-domain signal for a highest-power sub-carrier frequency. This highest power is compared to an average power of all other sub-carriers and a narrow-band interferer is detected when the highest power is significantly above the average. When the interferer is detected N times in a time period, a control layer adds this sub-carrier frequency to a removed list and recalculates filter coefficients to add a notch filter at the frequencies of the removed list. Updated filter coefficients are loaded into the filter to implement notch filters. When the current power of a sub-carrier signal on the removed list falls significantly below the average power, the sub-carrier is deleted from the removed list and coefficients recalculated to remove the notch filter.
