<P>PROBLEM TO BE SOLVED: To provide techniques for encoding and decoding data. <P>SOLUTION: Multiple code rates for a forward error correction (FEC) code may be supported, and a suitable code rate may be selected based on packet size. A transmitter may obtain at least one threshold to use for code rate selection, determine a packet size to use for data transmission, and select a code rate among the multiple FEC code rates based on the packet size and the at least one threshold. Multiple FEC codes of different types (e.g., Turbo, LDPC, and convolutional codes) may be supported, and a suitable FEC code may be selected based on packet size. The transmitter may obtain at least one threshold to use for FEC code selection and may select an FEC code among the multiple FEC codes based on the packet size and the at least one threshold. <P>COPYRIGHT: (C)2012,JPO&INPIT |
