Coding for efficient information transmission in optical and wireless systems

该奖项支持的长期研究计划专注于设计高效的编码和解码技术，以实现在各种信道类型（包括无线信道、光信道和分组网络信道）上的可靠信息传输。 挑战在于实现编码方案，其（a）具有接近信息理论极限的效率;并且（B）可以用实际算法进行编码和解码。 研究挑战的出现是因为不同的渠道往往需要完全不同的方法。 它成为至关重要的是要实现一个很好的理解的信道的操作，建立基本的限制，并构建最合适的编码方案。 由于差错控制编码是每个现代通信系统的核心组成部分，这项工作有可能提高现有和新兴通信系统的效率，为服务提供商提供竞争优势，并为用户提供更好的（更便宜，更快，更可靠）服务。

The long-term research program supported by this award is focused on devising efficient encoding and decoding techniques for reliable information transmission over a variety of channel-types, including wireless channels, optical channels, and packet-network channels. The challenge is to achieve coding schemes that (a) have an efficiency approaching information-theoretic limits; and (b) can be encoded and decoded with practical algorithms. Research challenges arise because different channels often require quite different approaches. It becomes essential to achieve a good understanding of the operation of the channel, both to establish fundamental limits and to construct the most suitable coding schemes. Since error-control coding is a central component of every modern communications system, this work has the potential to improve the efficiency of existing and emerging communications systems, giving service-providers a competitive advantage, and giving their users better (cheaper, faster, more reliable) service.
