Decodificante Turbo Architecture and method using an optimal Signal to noise ratio Constant or almost Constant

摘要

The use of a value of the ratio of Signal to noise of Constant or almost Constant reference, more accurately, to support the process of decoding the information sequences were encoded using Turbo Coding Techniques, in particular in a WCDMA receivers UMTS, improves the accuracy of the decoding process, andThe Link Quality and System Performance in general. This can be done through the use of SNR Reference generated, for example, The Power Control loop in the receiver.More specifically, this modifies the value of the SNR of reference, on the basis of various factors including, but not limited to, Graduation factor is applied to the Metric of the entrance of the Decoder, Power settings, the increases of processing, L The Speed of Encoding and / or Modulation Scheme.
