Abstract

Detect that circuit performs turbo detection process, to recover data symbols frame from the signal received, the data symbols of the frame have been subjected to the markoff process effect that the data symbols with the frame in the signal received depend on the effect for the one or more TA data code elements that can be expressed as the grid with multiple grids level during the transmission.The detection circuit includes multiple treatment elements, and one of grid level of the dependence of the data symbols of each in the treatment element with representing the frame according to the markoff process is associated, and each in the treatment element is configured as:Each received in one or more of one or more soft-decision-values corresponding with the one or more data symbols for being associated with the grid level, and described treatment element is configured as:In a clock cycle, the fixed-point data of the priori soft-decision-value for one or more of data symbols is just being detected for fixed-point data from grid level to state measurement and expression after reception expression priori forward state metric priori.For each in multiple clock cycle of the turbo detection process, the detection circuit is configured as:Each in the treatment element for representing grid level, handle the prior information that one or more of data symbols are just being detected for the grid level for being associated with the treatment element, and the external soft-decision-value corresponding with one or more of data symbols is provided, for the following clock cycle of the turbo detection process.
