Abstract: An Orthogonal Frequency Division Multiplexing, OFDM, transmitter comprises a signalling data generator (113) which generates a set of data symbols indicative of physical layer characteristics of data transmissions from the OFDM transmitter (100). A first symbol generator (115) and second symbol generator (117) generates a first and second OFDM signalling symbol by allocating the set of data symbols to subcarriers. The allocation of the physical layer data symbols to subcarriers is different for the first OFDM signalling symbol and the second OFDM signalling symbol. A data packet generator (105) and transmitter (101) generate a data packet and transmit this to an OFDM receiver (300). The OFDM receiver (300) determines the physical layer data symbols by combining the data symbols of corresponding subcarriers of the first and second OFDM signalling symbols and uses the resulting information to decode the user data of the data packet.

Abstract: A detector or a modulator for converting between optical and radio frequency signals comprising an optical guide (11 to 14) for propagating two optical signal components having frequencies that differ by an amount corresponding to a radio frequency and a microstrip radio signal guide (15, 16) for propagating a radio signal at the radio frequency, the microstrip radio signal guide being in travelling-wave coupling with an interaction zone (14) of the optical guide comprising material in which interaction between the optical signal components and the radio signal occurs. The microstrip radio signal guide element (15, 16) comprises an electrically conductive strip (15) juxtaposed with and extending along the interaction zone (14) on one side thereof and an electrically conductive ground plane (16) juxtaposed with and extending along the interaction zone (14) on an opposite side thereof. Transition radio signal guide elements (20, 21) in the form of Vivaldi antennas extending transversely to the microstrip (15) connect the microstrip radio signal guide element (15, 16) with a rectangular section wave-guide (18) and a matched load. Each of the transition radio signal guide elements (20, 21) comprises an opening of progressively varying width formed in the electrically conductive ground plane of the microstrip guide (16). Radio frequency signal resonators (24 to 27) extend the ends of the microstrip (15) and the small ends of the Vivaldi antennas.

Abstract: An orthogonal frequency division multiplex (OFDM) wireless communication system supports two OFDM communication modes of operation. A first OFDM communication mode of operation utilises a first respective communication bandwidth and a second OFDM communication mode of operation utilises a second communication bandwidth that incorporates the first communication bandwidth and at least one side carrier of the first communication bandwidth, where the at least one side carrier is arranged to carry no power in the first mode of operation. Signalling information is communicated in the at least one side-carrier in the second mode of operation, thereby indicating that the second mode of communication is to be used.

Abstract: An optical to radio frequency detector comprising an optical guide (11 to 14) for receiving two optical signal components having frequencies that differ by an amount corresponding to a radio frequency, and a radio signal guide (15, 16) coupled with an interaction zone (14) of the optical guide for propagating a radio signal from the interaction zone at the radio frequency. The interaction zone (14) of the optical guide comprises an interaction material presenting a second-order non-linear optical polarisation characteristic to the propagation of the optical signal components, and the radio signal guide (15, 16) is in travelling-wave coupling with the interaction zone. The interaction material includes electrically orientated diazobenzene. The radio signal guide (15, 16) comprises an electrically conductive strip (15) juxtaposed with and extending along the interaction zone (14) on one side thereof and an electrically conductive ground plane (16) juxtaposed with and extending along the interaction zone (14) on an opposite side thereof.

Abstract: An antenna arrangement comprising at least a first antenna element 101 having a geometric shape corresponding to a first spiral transformation of a first geometric fractal 107. The antenna arrangement may further comprise a second antenna element 103 having a geometric shape corresponding to a second spiral transformation of a second geometric fractal 109. The first and second geometric fractals 107, 109 may be the same or different fractals. The antenna arrangement may in particular provide improved wideband performance and a compact size and is suitable for Ultra WideBand (UWB) applications.
