Title:
DATA TRANSMISSION APPARATUS AND TRANSMISSION CODE GENERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2008/059588
Kind Code:
A1
Abstract:
A transmitter (1) comprises a scrambler part (14) that scrambles data such that the
number of appearances of "0" of input data is substantially equal to
the number of appearances of "1" of the input data; a bit sequence converting
part (15) that provides a bit data, which guarantees the maximum number of series
of serial bit sequences of the scrambled data, and converts control information
to a bit data of a fixed value; a synchronization timing generating part (16) that
divides transport data and converts the divided pieces of transport data to data
blocks; and a test bit calculating/imparting part (17) that imparts test data
of error correction to some of the data blocks. A receiver (3) comprises an error
bit calculation part (23) that performs an error test/error correction processing
based on the test bits imparted to the data blocks; an error bit correcting part
(25); a bit sequence converting part (26) that extracts a fixed-value bit pattern
of control data from the bit sequences of the data blocks, converts the extracted
fixed-value bit pattern to the control information and discriminates between
the data and the control information; and a descrambler part (27) that reconverts
the scrambled data to the data before the scrambling.
