Title:
【発明の名称】データ受信装置
Document Type and Number:
Japanese Patent JP3325735
Kind Code:
B2
Abstract:
A data signal composed of a desired signal faded and delayed and an interference signal faded and delayed is received by a pair of antennas. A direct component of the interference signal and a delay component of the desired signal are removed from the data signals received by the antennas in a decision-feedback type of desired signal equalizing unit, and the direct component of the desired signal and the delay component of the interference signal are removed from the data signals in a decision-feedback type of interference signal equalizing unit. Also, a delay component of the interference signal is removed in the desired signal equalizing unit by subtracting a replica of the delay component of the interference signal produced in a backward tap from a demodulated interference signal produced in the interference signal equalizing unit in a previous operation, and a delay component of the desired signal is removed in the interference signal equalizing unit by subtracting a replica of the delay component of the desired signal produced in another backward tap from a demodulated desired signal produced in the desired signal equalizing unit in the previous operation. Therefore, the demodulated desired signal agreeing with the desired signal is output from the desired signal equalizing unit, and the demodulated interference signal agreeing with the interference signal is output from the interference signal equalizing unit.
