摘要： A communication system including a first station having at least two first narrow beam antennas and a second station having at least two second narrow beam antennas. The first and second stations establish a first communication path for wireless communication via a pair of first and second narrow beam antennas. When communication via the first communication path is disturbed by obstacles, the first and second stations automatically establish at least one alternative communication path, which is spatially different from the first communication path, for wireless communication using the at least two first narrow beam antennas and the at least two second narrow beam antennas.

摘要： The present invention relates to a device (10) for receiving signals in a wireless orthogonal frequency division multiplex (OFDM) system and to a channel estimation method in such a system. The data symbols and pilot symbols are transmitted in frequency subcarriers and timeslots, whereby pilot symbols are transmitted in a continuous stream within at least one frequency subcarrier. A channel estimation for a data symbol is performed on the basis of received pilot symbols using a filter including a common phase error correction value from the continuous stream pilot symbol in the same timeslot as the data symbol to be channel estimated.The present invention thereby enables a correct and efficient channel estimation including a common phase error correction to be performed.
