摘要： Provided is a transmitter and a receiver for a high-throughput wireless communication system. The transmitter includes a baseband transmitter, a DIF transmitter, and a RF transmitter. The baseband transmitter performs a MAC protocol process on transmission signals and reception signals and processes the transmission signals by dividing an entire transmission band into n bands in a physical layer process of the transmission data, where n is a natural number. The DIF transmitter combines transmission signals of each band from the baseband transmitter and outputs m channel signals corresponding to a number of transmission antennas, where m is a natural number. The RF transmitter modulates each of the channel signals transferred from the DIF transmitter and transmits the modulated signals through m antennas.

The method includes the operations of: (a) obtaining a first bit of a first minimum value among input values, the number of input values being equal to the number of degrees of the check node, by performing an AND operation on first bits of the input values, the first bits being most significant bits of the input values; (b) obtaining result values by switching and sequentially performing an XOR operation and an OR operation on the first bit of the first minimum value and each of the first bits of the input values; and (c) performing operations (a) and (b) on the result values set as input values and performing operations (a) and (b) a number of times corresponding to the number of bits of each input value, that is, repeating until last bits are set as input values, to thereby obtain the first minimum value, the last bits being least significant bits of the input values. Accordingly, the complexity of hardware is reduced, and super high-speed processing is possible.
