APPARATUS AND METHOD FOR SPACE FREQUENCY BLOCK CODING IN MULTIPLE INPUT MULTIPLE OUTPUT SINGLE CARRIER WIRELESS COMMUNICATION SYSTEM

摘要

present invention multiple-input multiple-output (MIMO: Multiple Input Multiple Output) single carrier (Single Carrier) wireless communication system in, and a block encoder for encoding the symbols, block collection interval for a transmission signal coded symbols, and the diastolic expansion of repeating the symbol vector by a distance that is required is collected in the frequency domain, the repeat to be orthogonal to one another in the time domain inserting a zero in the extended symbol vector inserted tile, and then multiplied by the phase component in the 0 symbol inserted in the frequency domain vector to be orthogonal to one another, by combining the symbol vector, and a combiner for generating a transmission signal per antenna , a time domain repetition (repetition), and "0" insertion, and the phase-frequency space block coding (SFBC: Space-Frequency Block Coding) using the changed combined vector by performing, low PAPR (Peak to Average Power Ratio) maintains the block at the same time coding gain can be achieved.
