Hi,

Working well with soft symbols. I'm currently using the layered decoder, Self-Corrected Update and OffsetMinSumAlgorithm. What are the recommended settings for low SNR & MER signals irrespective of CPU load?

You can use the product-sum algorithm and the flooding schedule to get the most robust performance. But in practice, that's not really worth it. The default settings are already good enough and fast.

Thanks, I'll try SumProductAlgorithm. I have some very marginal recordings I can use for testing.

Closed, many thanks
