摘要： A multipoint relay (MPR) wireless network may include spaced apart nodes, with each node including wireless transceiver circuitry, beacon circuitry, and a controller coupled to the wireless transceiver circuitry and beacon circuitry. The controllers may be configured to operate the beacon circuitry to determine a respective link strength metric for each potential link between nodes, assign a set of nodes from among the plurality of nodes to function as gateway nodes and assign other individual nodes to communicate via respective gateway nodes based upon the respective link strength metrics to define the MPR network so that one-hop links have a strongest link strength metric, and operate the wireless transceiver circuitry for communications over the MPR network.

摘要： A Radio Frequency (RF) receiver may include a lower-order phase shift keying (PSK) demodulation circuit configured to generate at least one locking parameter when performing a lower-order PSK demodulation of an RF receive signal having an interfering PSK signal component. A higher-order PSK demodulation circuit has a higher order than the lower-order PSK demodulation circuit, and locks to the RF receive signal using the at least one locking parameter from the lower-order PSK demodulation circuit. The higher-order PSK demodulation circuit performs the higher-order PSK demodulation of the RF receive signal based upon locking to the RF receive signal to determine the interfering PSK signal component.

摘要： Systems and methods for mitigating the effect of in-band interference. The methods comprise: receiving a signal comprising at least one interfering signal component; generating a soft value for each symbol in at least one interfering signal component; and using the soft values to cancel at least one interfering signal component from the signal to mitigate the effect of interference. The soft value represents a most likely value for the symbol which is obtained by: determining a probability metric between an actual value of the symbol and each of a plurality of possible symbol values using a scaling value representing an estimate of the noise level in the signal received by the device; generating current local probabilities for the plurality of possible symbol values using the probability metric; and using the current local probabilities to determine the soft value.
