    • PURPOSE: A repetitive channel equalizer based on an EST(Energy Spreading Transform) performing repetitive channel equalization based on EST in a MIMO system is provided to obtain maximum diversity and maximum transform efficiency. CONSTITUTION: An IEST(Inverse EST) unit(302) performs EST reverse conversion about the output signal of a channel equalizer. A determination unit(304) determines a symbol level about the output signal of the IEST unit. An inter-symbol interference canceller(310) cancels inter symbol interference component through a feedback by using the signal determined from the determination unit. An intra-symbol interference canceller(312) cancels intra symbol interference component by using the signal determined from the determination unit.

    • PURPOSE: A data processing method for a communication system in which CDD(Cyclid Delay Diversity) technique and EST(Energy Spreading Transform) based equalization technique is applied, and a transmitting device and a receiving device thereof are provided to more efficiently transceive a signal. CONSTITUTION: A receiving side control unit(140) calculates interference and noises per signal of the received signal. The receiving side control unit determines an index for determining a delay value for each antenna considering the calculated result. A receiving side transmitting unit(164) transmits the determined index to a transmission side. The receiving side control unit calculates a maximum value among possible values of the interference and noises per signal of the received signal. The receiving side control unit determines the index considering the maximum value.
