Normalisierung für Turbo-Dekodierung |
摘要 |
<p>Provides a normalizing apparatus that normalizes input signals to a turbo decoder without significantly increasing a size of a circuit. An input signal buffer (341) obtains a sum S for N pieces of input signal data I (i). An input data averaging part (342) obtains an average A by dividing the sum S by the number of data N. A divider (343) obtains normalized data I (i) / A by dividing the input signals I (i) by the average A. A weighting part (345) multiplies the normalized data I(i)/A with a weighting coefficient alpha , which is determined based on a ratio of a number of input data and a number of output data in rate matching. As a result, the normalization is made possible. Because a signal receiving quality does not need to be determined, an increase in circuit size is inhibited. <IMAGE></p> |
