INTER SYMBOL INTERFERENCE REDUCTION BY APPLYING TURBO EQUALIZATION MODE

摘要

The present invention relates to a receiving node, and to a related method for determining when to apply a turbo equalization mode to compensate for inter-Symbol Interference in a radio signal (sin) received over a radio channel (h1, h2) from a transmitting node (100). The method comprises decoding (810) the received radio signal (sin) into a decoded signal (445), determining (820) a current error level in the decoded signal (445), predicting (830) a turbo equalization gain based on instantaneous channel information of the radio channel (h1, h2) and deciding (840) whether to apply the turbo equalization mode depending on the predicted turbo equalization gain and the determined current error level in the decoded signal (445).
