摘要： A receiver having an array antenna estimates arrival directions of multiple paths that arrive with an angular spread. Consequently, arrival direction estimation accuracy can be ensured without increasing throughput even if the power every path is low by estimating an average arrival direction of an entire set of multiple paths having the angular spread from a result of one angular spectrum by multiple correlation operation units that perform mutual correlation operations with pilot signals for baseband signals received by the array antenna, a path detection unit that detects multiple arrival path receiving timings by generating a delay profile based on output of each of the correlation operation units, a path correlation value synthesis unit that synthesizes a correlation operation value calculated in the multiple correlation operation units and an arrival direction estimation unit that collectively estimates multiple path arrival directions using output of the path correlation value synthesis unit.

摘要： A wireless relay device and a wireless relay method are provided which can improve the utilization efficiency of resources. In the wireless relay device for relaying a signal between a base station and a mobile station, if a transmission section transmits an SRS in a subframe immediately previous to the backhaul subframe, an SRS setting section sets a last symbol of an access link subframe as a fake symbol in which the SRS that the mobile station transmits to the wireless relay device is not configured. A reception section receives the signal transmitted from the mobile station to the wireless relay device in a previous symbol of one of the fake symbol, and then a switching section switches to transmission from the wireless relay device to the base station. If the transmission section does not transmit the SRS in the backhaul subframe immediately previous to the backhaul subframe, the reception section receives the signal transmitted from the mobile station to the wireless relay device in the last symbol of the access link subframe, and then the switching section switches to transmission from the wireless relay device to the base station.

摘要： An A/D converter converts the signal received by an array antenna and frequency-converted to a digital signal by a frequency converter. A correlation detector uses the chip rate as a cycle frequency and calculates a cyclic correlation matrix of spread spectrum signals stored in data storage. A cycle frequency detector detects the cycle frequency of an interference signal output from A/D converter. A correlation detector uses the detection result of the cycle frequency detector as a cycle frequency and calculates a cyclic correlation matrix of the signal, which becomes an interference signal, using the signal output from A/D converter. A direction of arrival is estimated, using the cyclic correlation matrices calculated by correlation detector and the correlation detector calculates the respective eigenvalues and eigenvectors and estimates the directions of arrival of a spread spectrum signal and a signal, which becomes an interference signal.
