Abstract
International audience; Turbo codes are a well-known code class used for example in the LTE mobile communications standard. They provide built-in rate flexibility and a low-complexity and fast encoding. However, the serial nature of their decoding algorithm makes high-throughput hardware implementations difficult. In this paper, we present recent findings on the implementation of ultra-high throughput Turbo decoders. We illustrate how functional parallelization at the iteration level can achieve a throughput of several hundred Gb/s in 28 nm technology. Our results show that, by spatially parallelizing the half-iteration stages of fully pipelined iteration unroll...
