    摘要： The game table reading system 1 comprises: reading antennas 7 for each of a plurality of reading areas of a game table 2; read-restriction antennas 10 for each of the plurality of the reading areas, the read-restriction antennas 10 restricting the RFID tag embedded in a game token 5 placed in the corresponding reading area from being read by the reading antenna 7 corresponding to the other adjacent reading areas; a reading control device 9 that controls the reading antennas 7; and a read-restriction control device 12 that controls the read-restriction antennas 10. The read-restriction control device 12 causes the read-restriction antennas 10 corresponding to the reading areas adjacent to the reading areas corresponding to the reading antenna 7 that the reading control device 9 causes to read, in synchronization with the reading control device 9.

    摘要： One or more transmitters (TX1, ..., TXU; TX) and a receiver (RX) of a MIMO communication system (1) enable mitigation of a jammer (TXJ). The one or more transmitters (TX1, ..., TXU; TX) are configured to generate an embedded signal (X) by embedding a transmit signal (5) onto a secret subspace (subC) based on a secret unitary matrix (C; C1, ..., CU) which is accessible to the transmitters (TX1, ..., TXU; TX) and the receiver (RX), and to transmit the embedded signal (X) via MIMO communication having a legitimate channel matrix (H) to the receiver (RX). The receiver (RX) is configured to receive a receive signal (Y) which includes the embedded signal (X) and to process the receive signal (Y) for determining an estimate ( ~ S) of the transmit signal (5) by extracting the transmit signal (S) from the secret subspace (subC) using the secret unitary matrix (C; C1, ..., CU).

    摘要： A wireless communication system, which may be included in a warehouse facility, comprising base stations, remotely located terminal units and a base station controller. The base stations and the remotely located terminal units communicate data over operational wireless communication links between them. The base stations include respective in-channel detectors and out-of-channel detectors for detecting radar or other extraneous received signals. The in-channel detectors analyse signals over the operational communication links. The out-of-channel detectors include respective out-of-channel receiver elements that monitor possibly available channels alternative to the respective operational communication link channels. The base station controller registers whether channels are available or not for communication links, and allocates to the base stations respective target channel parameters including frequencies available for operational and alternative communication links. The base stations store the respective target channel parameters for available operational and alternative communication links.
