论文摘要
由于各种在沟通系统中的应用(例如同时的能量和信息传输),因此最近引起了窗户约束的代码(SECC)和滑动窗口约束代码(SWCC)的关注。在SECC中,每个CodeWod被分为较小的非重叠窗口,称为子块,并且每个子块都被限制为具有足够的能量。在SWCC中,能量限制在每个窗口都执行。在这项工作中,我们专注于二进制通道,从理论上讲,通过使用相对较高的重量代码来实现足够的能量,并在更一般的约束下(即限制的SECC和有限的SWCC)研究secc和swccs。我们提出了两种基于Knuth的平衡技术和序列替代技术,构建具有低冗余性和线性时间复杂性的这种代码。对于某些代码参数,我们的方法仅产生一个冗余位。我们还对设计代码的误差校正能力施加了最小距离约束,这也有助于减少解码过程中的误差传播。
The subblock energy-constrained codes (SECCs) and sliding window-constrained codes (SWCCs) have recently attracted attention due to various applications in communcation systems such as simultaneous energy and information transfer. In a SECC, each codewod is divided into smaller non-overlapping windows, called subblocks, and every subblock is constrained to carry sufficient energy. In a SWCC, the energy constraint is enforced over every window. In this work, we focus on the binary channel, where sufficient energy is achieved theoretically by using relatively high weight codes, and study SECCs and SWCCs under more general constraints, namely bounded SECCs and bounded SWCCs. We propose two methods to construct such codes with low redundancy and linear-time complexity, based on Knuth's balancing technique and sequence replacement technique. For certain codes parameters, our methods incur only one redundant bit. We also impose the minimum distance constraint for error correction capability of the designed codes, which helps to reduce the error propagation during decoding as well.
