    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 method for transmitting signals in a wireless communication system, in which signals are transmitted from a first communication device to a second communication device, said signals being transmitted in consecutive frames, each frame having a preamble section comprising preamble information, at least one of said first and said second communication devices having a narrow beam antenna which is adapted to be steered to different positions, each of said different positions corresponding to one of a number of different transmission paths from said first to said second communication device, comprising the steps of transmitting and receiving a first preamble section comprising preamble information enabling the estimation of a channel quality of a current transmission path, while said narrow beam antenna is in a current position corresponding to said current transmission path, steering said narrow beam antenna from said current position to a different position corresponding to a candidate transmission path, and transmitting and receiving a second preamble section comprising preamble information enabling the estimation of a channel quality of said candidate transmission path while said narrow beam antenna is in said different position. The present invention further relates to a corresponding transmission device as well as a receiving device.

    摘要： In a backscatter interrogator reception method, a continuous carrier signal with a frequency fc is sent from an interrogator to a tag device over a wireless link, the tag device transmits data to the interrogator using a modulated backscatter signal, and the received modulated backscatter signal is demodulated by the interrogator to retrieve the data transmitted from the tag device. According to the present invention, the interrogator estimates the phase and the amplitude of an inband interferer signal contained in the received modulated backscatter signal, generates a cancellation signal having the opposite phase and the same amplitude as the estimation of the inband interferer signal, and combines said cancellation signal with the received backscatter signal in order to reduce the influence of the inband interferer signal. In addition, a two-stage interferer cancellation scheme is proposed.

    摘要： In a backscatter interrogator reception method, a continuous carrier signal (P1) with a frequency fc is sent from an interrogator (100) to a tag device (110) over a wireless link, the tag device (110) transmits data to the interrogator (100) using a modulated backscatter (P2) signal, and the received modulated backscatter signal (P2) is demodulated by the interrogator (100) to retrieve the data transmitted from the tag device (110). According to the present invention, the interrogator (100) estimates the phase and the amplitude of an inband interferer signal contained in the received modulated backscatter signal (P2), generates a cancellation signal having the opposite phase and the same amplitude as the estimation of the inband interferer signal, and combines said cancellation signal with the received backscatter signal (P2) in order to reduce the influence of the inband interferer signal. In addition, a two-stage interferer cancellation scheme is proposed.
