    摘要: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which provide for an enhanced decoding system that utilizes a variable sequence decoding to demultiplex data streams at a receiver. For example, the receiver may utilize an erasures decoding when the number of unknown bits, such as dissimilar transmitted bits (e.g., ‘1 0’ or ‘0 1’), is below a threshold (which may be the Hamming distance D−1). Otherwise, if the number of dissimilar transmitted bits is above the threshold, a list decoding is utilized. If the list decoding does not produce a single result, but instead produces multiple possible results, selection logic may be employed. The selection logic may utilize an errors and erasures decoding of the possible results, a media decoding of the possible results, and/or the like.

    摘要: Disclosed in some examples are methods, systems, devices, and machine-readable mediums in which an ad-hoc neighbor group of wireless devices provides a retransmission service to a first wireless device in the neighboring group over an out-of-band wireless protocol. That is, a first transmission from a transmitter to the first wireless device over a first wireless protocol may be received by a second wireless device in a neighboring group of wireless devices. The second wireless device may then retransmit information (e.g., packets) from the first transmission to the first wireless device over a second wireless protocol and/or channel. Thus, for example, a second wireless device may receive a satellite signal sent to the first wireless device and provide a retransmission of the signal or information from the signal to the first wireless device over a Wi-Fi direct protocol.
