Patent ID: 7664046

Claim:
A mobile communication terminal, comprising: a Central Processing Unit (CPU) configured to set at least one or more predetermined parameters according to communication channel states; a Cyclic Redundancy Checksum (CRC) unit configured to add CRC bits to data to be transmitted based on the set at least one or more predetermined parameters and to then packet the data having the CRC bits; a channel coding unit including at least first and second channel coders configured to differently channel-code the packeted data based on the set at least one or more predetermined parameters; a Hybrid Automatic Repeat reQuest (HARQ) transmission/reception processor configured to process the channel-coded data output from the channel coding unit based on the set at least one or more predetermined parameters; a channel interleaver unit including at least first and second channel interleavers configured to differently channel-interleave the processed data output by the HARQ transmission/reception processor; a modulator configured to modulate the channel-interleaved data; and an antenna configured to transmit the modulated data, wherein the CPU is further configured to select one of the first or second channel coders based on the set at least one or more predetermined parameters before channel-coding the packeted data and to select one of the first and second channel interleavers based on the set at least one or more predetermined parameters before channel-interleaving the processed data such that the modulated data is transmitted using different channel-coding and channel-interleaving methods based on the set at least one or more predetermined parameters.
