Abstract: In connection with an RF communication system, exemplary aspects may involve a method and apparatus for use in a communication system in which a RF receiver may be detecting and processing a first signal in an RF channel. Thereafter, a second received signal may be detected, with the second received signal being assessed, by receiver circuitry, as stronger than the first received signal. In response to the assessment of the second received signal being stronger than the first received signal, the RF receiver circuitry may adjust the gain or signal amplification circuitry for continuing to process the second, stronger, received signal in place of the first, weaker, received signal.

Abstract: A radio frequency (RF) front end receives one or more symbols of a first frame transmitted by a transmitter. The RF front end determines that the one or more received symbols are correlated to one or more address symbols, where the one or more address symbols are each a time-domain signal of subcarriers that the transmitter transmits. The RF front end provides the received one or more symbols to a baseband system based on the correlation. The baseband system recovers bits of a second frame within the first frame based on the received one or more symbols.

Abstract: A network node for a wireless network and corresponding methods for reducing false collisions in a wireless network, a wireless network, a wireless sensor network and a smart building including a wireless sensor network. The network node includes a processor, memory and an antenna. The network node is operable promiscuously to monitor and maintain a record of transmissions and acknowledgements received by the network node. The network node is also operable to send information relating to the record to another node in the network for use by the other node in determining that a further node to which the other node sends transmissions is hidden from the network node. In another aspect the network node is operable to determine from information received from a second other network node, that a first other network node is hidden from the second other network node.

Abstract: A program is executed with a first programmable device (10). Device operating points such as power supply voltage and/or clock frequency are adapted dependent on the states reached by the device during execution. Operation of programs that may have been sold after the device has been supplied to users is optimized by executing the computer program on each of a plurality of programmable devices (10) like the first programmable device, and collecting statistical data associated with the execution states encountered during execution by the plurality of programmable devices (10). Each of the plurality of programmable devices (10) collects its own statistical data and uploads the collected information to a common profiling apparatus (14). The profiling apparatus assigns device operating points to respective ones of the execution states, using an optimization that depends on the combined statistical data from the plurality of programmable devices (10).
