  • Publication number: 20200195344
    Abstract: Examples relating to techniques for wireless communications, e.g., visible light communication, VLC, are disclosed. In particular, there is disclosed a communication device for communicating with a plurality of other devices, using a wireless link. The device provides individual reference signals using a number of subcarriers or time slots in accordance to the optical clock reference and the number of transmitting devices in the set or streams to be transmitted in parallel. The device defines the position of subcarriers or of signals at the time slots in accordance to an identification number associated to an individual device within the whole set of transmitting devices or in dependence on an identification number identifying a specific stream or transmitter. The device transmits the reference signal which enables the plurality of receiving devices to identify the signal coming from the individual communication device in the whole set of devices.

  • Patent number: 10355705
    Abstract: It is provided a signal processing system, comprising at least a first, a second and a third digital-to-analog converter (DAC); a processing unit configured for splitting a sampled signal into a first and a second signal corresponding to different frequency portions of the sampled signal, transmitting the first signal to the first DAC, splitting the second signal into a first and a second subsignal and transmitting the first subsignal to the second DAC and the second subsignal to the third DAC, the first subsignal corresponding to the real part of the second signal and the second subsignal corresponding to the imaginary part of the second signal; an IQ mixer configured for mixing an analog output signal of the second DAC and an analog output signal of the third DAC and a combiner for combining an analog output signal of the first DAC and an output signal of the IQ mixer.

  • Patent number: 10326524
    Abstract: A system for providing a wireless communication with a mobile device includes a plurality of frontends coupled to a central point, each of the plurality of frontends configured to provide for a wireless communication with the mobile device, and a network controller coupled to the central point. The network controller includes a data flow control device configured to control the data flow between each of the frontends and the central point, the data flow control device being configured to operate responsive to a control signal from the network controller, the control signal indicating which of the plurality of frontends serves the mobile device.
