Foundational — DSP Notes: On Discrete Sequences and Systems (Part I)

"Learning digital signal processing is not something you accomplish; it's a journey you take."-- Richard G. Lyons Our last post (article III) covered radio frequency spectrum bands and their applications. However, the primary reason for starting this series is to develop both theoretical and practical knowledge of DSP. Over time, readers can expect an Applied … Continue reading Foundational — DSP Notes: On Discrete Sequences and Systems (Part I)

Advanced – Maximum A Posteriori Estimation Decoding

(Part One: AWGN Model) A useful example of MAP estimation was NASA's 1997 US patent, pertaining to the invention of a MAP decoder for digital communications. MAP decoding is a probabilistic decoding method that selects the most likely transmitted sequence given the received sequence and the channel's statistical properties. It is fundamental in the field … Continue reading Advanced – Maximum A Posteriori Estimation Decoding
