Abstract: A method of processing data received over a channel includes receiving data representing probabilities associated with a plurality of variables and receiving a parity check matrix associated with a factor graph which includes variable nodes and check nodes connected by edges. After each exchange of messages between the variable nodes and check nodes, messages are calculated based on messages received at the variable nodes and permuted messages to be sent from the variable nodes in the next iteration are calculated by applying a permutation to the calculated messages. The permutation is of a set of permutations which map each codeword of the set of codewords onto a different codeword of the set of codewords. Soft values associated to variable nodes can be accumulated over two iterations of the message exchange processing.

Abstract: A method of allocating energy resources in a network signalling node during an interval of time the network signalling node having internal processing components for maintaining operation of the node and relaying components for relaying data between other nodes in the network. The method comprises determining an amount of energy available for use by the node during the interval, determining a willingness parameter that defines the willingness of the node to supply energy to the relaying components during the time interval, determining, based on the willingness parameter, a portion of the available energy to allocate to the internal processing components during the time interval; and allocating the remainder of the available energy to the relaying components.

Abstract: Metering of a physical characteristic is described, in which a stochastic approach is taken. A random signal is generated on the basis of a metering signal, with a view to maximising a statistical distance between the two. The random signal and the metering signal are mixed together to obscure characteristics of the metering signal which could otherwise divulge private information to third parties.

Abstract: The embodiments provide a transceiver, a method and a system for transmission of one or more signals in a wireless communication network. The transceiver according to the described embodiments being capable of collecting channel characteristics based on a received signal from another transceiver in the network; predicting a transmission mode for a subsequent signal transmission on the basis of said collected channel characteristics by determining an interference level of said received signal and estimating an interference level for the subsequent transmission based on the determined interference level and one or more parameters of the received signal, wherein the transmission mode for the subsequent transmission is predicted based on the estimated interference level. The transceiver being further configured to adapt transmission parameters of one or more subsequent transmissions based on the predicted transmission mode.
