Abstract: Devices and methods described herein decode a sequence of coded symbols by guessing noise. In various embodiments, noise sequences are ordered, either during system initialization or on a periodic basis. Then, determining a codeword includes iteratively guessing a new noise sequence, removing its effect from received data symbols (e.g. by subtracting or using some other method of operational inversion), and checking whether the resulting data are a codeword using a codebook membership function. This process is deterministic, has bounded complexity, asymptotically achieves channel capacity as in convolutional codes, but has the decoding speed of a block code. In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted. Abandonment decoding nevertheless approximates maximum likelihood decoding within a tolerable bound and achieves channel capacity when the abandonment threshold is chosen appropriately.

Abstract: Described are concepts, systems, devices and methods that enhance decoding performance of channels subject to correlated noise. The concepts, systems, devices and methods can be used with any combination of codes, code-rates and decoding techniques. In embodiments, a continuous realization of effective noise is estimated from a lead channel by subtracting its decoded output from its received signal. This estimate is then used to improve the accuracy of decoding of an otherwise orthogonal channel that is experiencing correlated effective noise. In this approach, channels aid each other through the post-decoding provision of estimates of effective noise. In some embodiments, the lead channel is not pre-determined, but is chosen dynamically based on which of a plurality of decoders completes first, or using soft information including an estimate of effective noise that is least energetic or most likely to have occurred.

Abstract: An augmented connection graph can be created based on a task to be performed by a fog computing node by augmenting a connection graph representing plurality of IoT devices and connections among them. The augmenting can include adding to the connection graph data type nodes representing types of data processed by the fog computing node and adding connections between the data type nodes and IoT devices that generate the type of data represented by the respective data type nodes. A connection can be added between each pair of the IoT devices that are not currently connected and for which a level of correlation between the pair of IoT devices at least equals a threshold value. Based on the augmented connection graph, at least one of the IoT devices to assign to the fog computing node can be determined and assigned to the fog computing node.

In various embodiments, soft information is used to generate a symbol mask that identifies the collection of symbols that are suspected to differ from the channel input, and only these are subject to guessing. This decoder embodies or approximates maximum likelihood (optionally with soft information) decoding for any code. In some embodiments, the decoder tests abounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted.

Abstract: A method is disclosed for transmitting data between a source node and destination node connected via multiple paths of a heterogeneous network, at least one of the paths delivering packets with a non-deterministic delivery time. Data is divided into frames, each frame comprising a number of packets, where processing by the destination node of an information packet p is conditional on receipt of the data for any information packet i where i<p. A number of sequential transmission slots s, each for transmitting a given packet p of a frame, are allocated for each network path k. A set D of possible assignments of packets to transmission slots for a frame are provided. The method comprises determining an assignment x with minimum in-order delivery delay of said packets based on expected arrival times of packets to their destination and expected reordering delay for packets. Packets are then transmitted in accordance with the determined assignment x.
