Abstract
Embodiments of the invention relate to a method, apparatus and computer readable storage medium wherein the method comprises; padding a data block of a data structure to enable encoding of the data block; encoding the data block; reducing the size of the encoded data block; and spreading the data block.
Claims20
A method comprising:
- padding a data block of a data structure to form a padded data block;
- encoding the padded data block with an encoding algorithm to produce an encoded data block having a first code rate;
- reducing a size of the encoded data block to produce a reduced encoded data block having a second code rate lower than the first code rate;
- and
- spreading the reduced encoded data block to produce a modified encoded data block.
2 more elements
An apparatus comprising:
- a padding circuit configured to pad a data block of a data structure to form a padded data block;
- an encoder configured to encode the padded data block with an encoding algorithm to produce an encoded data block having a first code rate;
- a shortening circuit configured to reduce a size of the data block after encoding to produce a reduced encoded data block having a second code rate lower than the first code rate;
- and
- a spreader configured to spread the reduced encoded data block to produce a modified encoded data block.
2 more elements
a non-transitory computer-readable storage medium encoded with instructions that, when executed by a processor enable:
- padding a data block of a data structure to form a padded data block;
- encoding the padded data block with an encoding algorithm to produce an encoded data block having a first code rate;
- reducing a size of the encoded data block to produce a reduced encoded data block having a second code rate lower than the first code rate;
- and
- spreading the reduced encoded data block to produce a modified encoded data block.
2 more elements
An apparatus comprising:
- a padding circuit configured to concatenate zeros to a header of a data structure to form a padded header;
- an encoder configured to create a low density parity check codeword by generating parity bits for the padded header, wherein the codeword has a first code rate;
- a shortening circuit configured to remove bits of the codeword to create a reduced length codeword having a second code rate lower than the first code rate;
- a modulator configured to modulate the reduced length codeword to form a modulated codeword;
- and
- a spreader configured to spread the modulated codeword to produce a modified codeword.
