First Claim
Patent Images
1. A de-interleaver for restoring interleaved data, comprising:
- a data storage section storing data before de-interleaving;
a first storage section storing additional data information containing a size and an added position of additional data to the data before de-interleaving; and
a second storage section storing a permutation rule of first de-interleaving, wherein de-interleaving is performed on the data stored in the data storage section based on the additional data information stored in the first storage section and the permutation rule stored in the second storage section.

Abstract
A de-interleaver has a TTI frame buffer storing a TTI frame before de-interleaving, a P bit information table storing P bit information containing the size and added position of P bits to be added to the TTI frame before de-interleaving, and a permutation rule table storing permutation rules of de-interleaving. The de-interleaver performs de-interleaving on the data stored in the TTI frame buffer based on the P bit information stored in the P bit information table and the permutation rules stored in the permutation rule table.

9. A mobile communication terminal which performs de-interleaving on received data, comprising:
-
an antenna receiving a radio signal;
a demodulation section demodulating a radio signal received by the antenna;
a data storage section storing a received data demodulated by the demodulation section;
a first storage section storing additional data information containing a size and an added position of additional data to the received data; and

13. A de-interleaving method for received data in a wideband code division multiple access (W-CDMA) system, comprising:
-
acquiring additional data information indicating a transmission gap length and containing a size and an added position of additional data to be added to the received data;
determining an output sequence of the received data after de-interleaving based on the additional data information and a predetermined permutation rule; and
outputting the received data according to the determined output sequence. - View Dependent Claims (14, 15)
