无线体域网具有广阔的应用前景，对提高全民生活质量、健康水平具有重要作用。为了保证生物信息传输的可靠性，在无线体域网中使用信道编码技术必不可少。由于用于人体，无线体域网对功耗有严格的要求。因此，在设计信道编码方案时必须尽可能降低功耗，并且更有效地利用资源。在这方面，无线体域网的信道编码技术还有许多值得探索的地方。本项目针对Raptor码在无线体域网中的应用，从码组构造、解码性能以及不等差错保护等方面入手，研究无线体域网中的高性能低功耗信道编码技术。本项目将重点研究无线体域网信道模型下结构化Raptor码的构造方法、根据不同终端特性设计的解码算法以及具有不等差错保护功能的Raptor码结构。研究成果有望在无线体域网中实现更先进的信道编码技术，以提高系统整体性能。这对无线体域网的进一步推广具有重要的理论意义和实用价值。

Wireless Body Area Network (WBAN) has a variety of applications and is important for improving quality of life and health conditions of the entire people. To guarantee the transmission reliability of biometric data, it is essential to use channel coding technologies in WBAN. Since applied to human body, WBAN has stringent low-power requirements. Therefore, when designing channel coding schemes, we should lower power consumption as much as possible and make a better use of resources. In these areas, there is a lot of space to improve for channel coding technologies in WBAN. This project focuses on the use of Raptor codes in WBAN and researches on high performance and low power channel coding technologies in WBAN in respect of code construction, decoding, unequal error protection, etc. The project will propose code construction method for structured Raptor codes over WBAN channel models, decoding algorithms based on characteristics of receivers, and structure of Raptor codes with unequal error protection properties. The research fruits of this project are expected to lead to more advanced channel coding technologies and improve the overall performance of WBAN, which is important in both theory and practice for WBAN to become more widespread.
