适用于低功耗和低成本设备的统一极化解码器平台

A unified polar decoder platform for low-power and low-cost devices

摘要:

在本文中,我们设计了一个极化解码平台,为不同的应用场景,需要低成本和低功耗的通信。具体地,诸如连续消除(SC)、SC列表(SCL)和Fano解码器之类的流行的极化解码器都在相同的架构下被支持。与促进并行性的高吞吐量或低延迟解码器不同,这种架构通过重复调用由核心模块执行的“子进程”来促进串行化。由此产生的串行SCL-8解码器仅为SC解码器的3倍大。通过资源共享和自适应解码技术等降低成本和功耗。我们进行了性能仿真和硬件实现,以评估实际的芯片面积和能耗。

英文摘要:

In this paper, we design a polar decoding platform for diverse application scenarios that require low-cost and low-power communications. Specifically, prevalent polar decoders such as successive cancellation (SC), SC-list (SCL) and Fano decoders are all supported under the same architecture. Unlike high-throughput or low-latency decoders that promote parallelism, this architecture promotes serialization by repeatedly calling a ``sub-process'' that is executed by a core module. The resulting serial SCL-8 decoder is only 3 times as big as an SC decoder. Cost and power are minimized through resource sharing and adaptive decoding techniques, etc. We carried out performance simulation and hardware implementation to evaluate the actual chip area and energy consumption.
