    摘要： A method to provide robustness against noise and interference in wireless communications, a transmitter and computer program products, involving sending to a receiver (13), through a wireless channel (12), information using a constant-envelope waveform with complex baseband representation of the form s[n]=Ac exp{jϕ[n]}. The phase ϕ[n] following the expression ( φ  [ n ] - φ  [ n - 1 ] ) = 2  π   m · ∑ k = k 0 + 1 k 0 + N a , F   M + - 1  x  [ k ]  exp  ( j   2  π   kn N ) , and the wireless channel has an Additive White Gaussian Noise component and flat-fading conditions, wherein the transmitter (110) calculates a FFT length, N, and a number of active positive subcarriers, Na,FM+, needed in order to have a given improvement in the signal to noise ratio at the active positive subcarriers of the instantaneous frequency spectrum containing the information; calculates a cutoff subcarrier k0 needed to overcome Doppler, phase noise and carrier frequency offset impairments at the receiver side, and generates a complex baseband signal waveform of the form s[n]=Ac exp{jϕ[n]} carrying information with the FFT length, number of active positive subcarriers and cutoff subcarrier.

    摘要： A method and device for virtualization of terminal devices in mobile communications networks. The present invention introduces the idea of a completely virtualized terminal device. Any interaction through the user interface can trigger appropriate actions, such as connecting to a peer device, but the behaviour of the terminal device would be fully controlled by an operator's device virtualization node which would perform the appropriate actions with the peer device on behalf of the terminal device, irrespective of the type of connection. The complete functionality of the device is virtualized making it independent of the actual device capabilities so the mobile users can get rid of any actual constraints imposed by the terminal device.

    摘要： Methods, a base station and computer programs for performing multiple access in wireless OFDM cellular systems over multipath wireless channels considering both space and frequency domains,The base station 100 comprises a large number of antennas 103 in the form of a two-dimensional array and transmits a given number of signals to a number of users 106, so that each one receives its intended signal (or set of intended signals) without interference to/from the other users 106. The base station 100 includes a scheduler in space-time-frequency dimensions 101 as well as an orthogonal space-frequency processing technique 102 for addressing the users 106. The cellular scenario is assumed where the wireless channel 105 presents significant multipath, thereby resulting in multiple signal components being received by each user 106. Orthogonality of the beams is achieved upon transmission by properly discretizing the spatial domain, while inter-user interference is avoided by exciting only those beams that result in multipath components received by one single user 106.
