On the OutageConstrained Rate of SkipSliding Window Codes We consider binary skipsliding window (SSW) codes which satisfy certain weight constraints over a skipsliding window. When onoff keying is employed, these weight constraints ensure realtime energy content in the transmitted signal. For a given energy requirement and battery size at an energy harvesting receiver, we investigate the maximum achievable rate using SSW codes which avoid energy outage at the receiver. The SSW codes generalize sliding window constrained (SWC) codes and subblock energy constrained (SEC) codes; we show that SSW codes with window length equal to twice the skiplength can outperform both SWC and SEC codes in terms of outageconstrained rate.

SCFlip Decoding of Polar Codes with High Order Error Correction Based on Error Dependency The successive cancellation flip (SCFlip) decoding algorithm arose as a valid lowcomplexity decoding algorithm for polar codes, however its decoding capabilities are still far away from list based decoders. In this paper, we propose an improved SCFlip multiple error decoding framework based on error dependency, and specialize it for the twoerror correction case. We propose to generate different lists of second error locations based on the index of the expected first errors. The inherent flexibility of this approach allows it to be modified for a desired tradeoff between performance and complexity. Two second errors list construction approaches are presented, and are shown to yield gains over the original SCFlip decoder at the same decoding complexity.
