A maximum A posteriori estimator with fast sigma calculator

Forward and backward recursive calculations in a maximum a posteriori decoding process are performed in parallel processes, rather than sequentially, allowing the a posteriori transition probabilities to be calculated in the same time interval as the recursions, thereby reducing decoding latency and...

Zusammenfassung:Forward and backward recursive calculations in a maximum a posteriori decoding process are performed in parallel processes, rather than sequentially, allowing the a posteriori transition probabilities to be calculated in the same time interval as the recursions, thereby reducing decoding latency and required memory.
