CMOS技术的不断缩小威胁着未来嵌入式系统芯片的可靠性。我们开发了一种新的可靠的无线通信系统的设计方法，利用系统性能，硬件可靠性和实现复杂性的相互权衡。我们的跨层方法结合了硬件层面的弹性技术与算法技术，利用接收器中的可用灵活性。通过只从对系统行为有很大影响的硬件错误中恢复，可以最大限度地减少开销。我们将我们的新方法应用于双迭代MIMO-BICM接收机，它属于当前通信标准中最复杂的系统。
Continued progressive downscaling of CMOS technologies threatens the reliability of chips for future embedded systems. We developed a novel design methodology for dependable wireless communication systems which exploits the mutual trade-offs of system performance, hardware reliability, and implementation complexity. Our cross-layer approach combines resilience techniques on hardware level with algorithmic techniques exploiting the available flexibility in the receiver. The overhead is minimized by recovering only from those hardware errors that have a strong impact on the system behavior. We apply our new methodology on a double-iterative MIMO-BICM receiver which belongs to the most complex systems in current communication standards.
