Patent Images
1. A transmitting end device comprising:
- a processor configured to;
attach a first error checking code to a first type signal block to produce sequence,segment the sequence into one or more second type signal blocks when the length of the sequence is longer than a predetermined length, wherein a length of each of the second type signal blocks corresponds to a specific length equals to the predetermined length minus a length of a second type error checking code,attach the second type error checking code to each of the second type signal blocks when the length of the sequence is longer than the predetermined length, andprepare a transmission signal based on each of the second type signal blocks; and
a transmitter configured to transmit the transmission signal to a receiving end device.

Abstract
The present invention provides for applying a cyclic redundancy check (CRC) to a data signal. The present invention includes attaching a first CRC to a first data signal block having a first length, segmenting the first data signal block attached with the first CRC into a plurality of second data signal blocks having a length shorter than the first length, respectively generating a second CRC for each second data signal block, and attaching the generated second CRC to the respective second data signal block. Moreover, the first CRC and second CRC may be generated from respectively different CRC generating polynomial equations.
