Abstract
An apparatus and method for improving a HARQ combining gain in a broadband wireless communication system are provided. The apparatus includes a seed information generator and a subcarrier allocator. The seed information generator randomly generates a seed value for changing a channel of a subcarrier and an interference pattern in a frame unit when a HARQ combining gain is not generated because an interference pattern is the same during a retransmission period. The subcarrier allocator allocates a subcarrier using the generated seed value.
