{"product_id":"monolithic-implementation-of-turbo-codes-von-antonio-mondragon-torres","title":"Monolithic Implementation of Turbo Codes","description":"\u003cp\u003eOne of the key aspects of turbo codes is that they use soft-input and soft-output values in the decoding stage. Thus no information is discarded until the algorithm has iteratively converged to a solution, at which time a hard decision is taken. The soft-input soft-output concept refers to infinite quantized or analog values in a natural form. This research work proposes CMOS integrated circuit implementations of both the encoding and the decoding algorithms. In particular it explores an all-analog decoder implementation that will naturally exploit the continuous nature of the received signals.The proposed analog decoder is based on the additive soft-input soft-output algorithm that can be naturally mapped into a multiple input floating gate transistors implementation. By taking advantage of the symmetric structure of the trellis generated by convolutional codes, every node in the trellis can have a direct analog counterpart that will mathematically solve the decoding algorithm in the analog domain.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783639704679\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783639704679","offer_id":39482452377693,"sku":"9783639704679","price":94.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/37365d9c-9421-4dde-8cd2-f161fdcabc08.jpg?v=1768979324","url":"https:\/\/shop.autorenwelt.de\/en\/products\/monolithic-implementation-of-turbo-codes-von-antonio-mondragon-torres","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
