The present project proposal addresses methods for distributed source coding. Recently, the theoretical concept of integer-forcing source coding, a modulo-based source coding, has been presented. However, up to now, it has been treated only as an information-theoretic concept and its asymptotic behavior has been analyzed. In the literature, there are very few results concerning the effectiveness of the method, corresponding implementation aspects, as well as advantages and disadvantages in comparison to established source coding strategies for the practice-relevant, low-dimensional case. Hence, the approach shall be analyzed and evaluated from an engineering perspective. On this basis, specific modulo-based coding schemes for lossy data compression will be designed. For this purpose, the duality between source coding and channel coding/equalization will be exploited. The diverse concepts and methods known in the field of lattice-based equalization can be beneficially transferred to the to the situation at hand.

目前的项目建议解决分布式源代码编码的方法。最近，基于模的信源编码，即整数强制信源编码的理论概念被提出。然而，到目前为止，它只是被视为一个信息论的概念，它的渐近行为进行了分析。在文献中，有很少的结果有关的有效性的方法，相应的实施方面，以及建立的源编码策略的实践相关的，低维的情况下相比的优点和缺点。因此，应从工程角度对该方法进行分析和评估。在此基础上，设计了具体的基于模的有损数据压缩编码方案。为此，将利用信源编码和信道编码/均衡之间的对偶性。在基于网格的均衡领域中已知的不同概念和方法可以有益地转移到手头的情况。
