摘要： Use of a more accurate, constant or quasi-constant reference signal-to-noise ratio value to support the process of decoding information sequences that have been encoded using turbo coding techniques, particularly in UMTS WCDMA receivers, enhances the accuracy of the decoding process and, in turn, link quality and overall system performance. This may be accomplished by exploiting the reference SNR, which is generated, for example, by the power control loop in the receiver. More specifically, the present invention modifies this reference SNR value based on various factors including, but not limited to, the scaling factor that is applied to the decoder input metrics, power settings, processing gains, coding rates and/or the modulation scheme.
