摘要： In a wireless base station device that communicates with a mobile device via an advance base station, the reception timing determination portion determines the reception timing of data that is transmitted by a mobile device that exists in a cell of the advance base station on the basis of the distance between the wireless base station device and the advance base station and the cell radius of the advance base station. The data reception portion receives data from the mobile device by performing a reception operation at the reception timing, the delay profile creation portion creates delay profiles on the basis of the received data, and the path detection portion detects paths from the mobile device on the basis of the delay profiles.

摘要： When an antenna receives a signal, the signal is inputted to delayers through a frequency converter, A/D converters, quadrature demodulators, filters and simultaneously is inputted to a MUX. The receiving signal inputted to the MUX is transmitted to an interference canceler panel, and the interference canceler panel generates both an interference replica signal and a symbol replica signal. The interference canceler panel demodulates the receiving signal for a channel corresponding to the symbol replica signal using both the interference and symbol replica signals. The interference replica signal generated by the interference canceler panel is transmitted to a transmitting/receiving panel and is inputted to interference elimination units. The interference elimination units eliminates interference components by subtracting the interference replica signal from the receiving signal delayed by the delayers and transmits the signal to a baseband signal processing panel.

摘要： A phase error detector in a base transceiver station detects a phase error caused by a Doppler shift in a received wave from a mobile station. A phase rotator rotates a phase of a transmission symbol in a base band region so as to cancel the Doppler shift, which occurs in a downlink from a base transceiver station to a mobile station based on the phase error detected by the phase error detector.
