摘要： 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.

摘要： A method and apparatus are provided for generating a code by quickly computing a state of a Linear Feedback Shift Register (LFSR) in a mobile communication system, in which a code for the communication system is generated including an n-stage LFSR and operating in sleep mode and active mode set at a preset time interval from the sleep mode. Current state values of the LFSR are combined with n different mask patterns such that the current state values are shifted by {20,21, . . . ,2n−1}. A combination result is provided as a new state value of the LFSR at an arbitrary time variably set in the sleep mode. To transform a current state value of the LFSR to a new state value after an arbitrary time, the code generation method employs a square and multiply algorithm without use of mask patterns.

摘要： A technique for avoiding reception performance deterioration caused by a tone interference that occurs at a position carrying a pilot signal in a wireless communication system is provided. A receiving end includes an operator for converting a time-axis signal into a frequency-axis signal, an extractor for generating channel values in positions carrying pilot signals among the frequency-axis signals, a compensator for compensating for a channel value of a position at which tone interference occurs by using at least one channel value of a position at which no tone interference occurs among the channel values.
