    Abstract: Method and system to dynamically associate spatial layers to beams in a FWA network operating in the millimeter-wave frequency range. A base station and a CPE are willing to wirelessly transmit and receive data through a wireless channel of the FWA network, the base station having beamforming capabilities henceforth generating multiple wireless beams. The base station performs all baseband wireless functions related for creating, keeping and managing the connections between the base station and the CPE at baseband level, wherein information is handled in the form of up to M spatial layer signals, and with no built-in capabilities for creation, detection or management of the beams. The base station also performs all necessary RF functions at millimeter-wave frequencies, including beamforming and conversion from complex baseband signals to RF signals and vice versa, and also couples the RF signals to the wireless channel.

    Abstract: 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.
