On the Outage-Constrained Rate of Skip-Sliding Window Codes

Abstract

We consider binary skip-sliding window (SSW) codes which satisfy certain weight constraints over a skip-sliding window. When on-off keying is employed, these weight constraints ensure real-time 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 skip-length can outperform both SWC and SEC codes in terms of outage-constrained rate.
