Title:
DATA PROCESSING DEVICE AND DATA PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/082060
Kind Code:
A1
Abstract:
This technology relates to a data processing device and a data processing method which enable more reliable generation of a valid address in interleaving. In a data processing device, a frequency interleaver for performing frequency interleaving calculates a first bit sequence generated by a first pseudo-random number generation unit for generating a random bit sequence, a second bit sequence generated by a second pseudo-random number generation unit for generating a random bit sequence, and an additional bit generated by a bit generation unit for alternately generating a bit that is 0 and a bit that is 1, and when a write address or read address comprising a random bit sequence is generated, the bit that is 0 and the bit that is 1 are alternately repeated as the most significant bit of the random bit sequence. This technology is applicable, for example, to a frequency interleaver for performing frequency interleaving.
