Abstract:
1. A transmitting apparatus for improving a Hybrid Automatic Repeat reQuest (HARQ) combining gain in a broadband wireless communication system, the apparatus comprising: a seed information generator configured to randomly generate a seed value for changing a channel of a subcarrier and an interference pattern in a frame unit, when the HARQ combining gain is not generated because an interference pattern remains unchanged during a retransmission period; and a subcarrier allocator configured to allocate a subcarrier using the generated seed value, wherein the seed information generator generates the seed value using a frame number and a range of a seed value allocated to a Base Station (BS), and wherein the seed information generator generates at least one of a seed value of a permutator and a seed value of a Pseudo Noise (PN) code generator, as the generated seed value.
