An apparatus for processing data symbols in a multi-carrier transmitter, includes a transmit pulse shaper and a transmit sub-band filter. The transmit pulse shaper is adapted to filter a plurality of data pulses with respective transmit pulse shaping filters. Each of the data pulses is associated with a respective carrier of the multi-carrier communication system. The transmit sub-band filter is adapted to perform sub-band filtering of the pulse-shaped data pulses. The sub-band filter and at least one of the transmit pulse shaping filters are correlated. This correlation may be achieved by jointly designing the sub-band filter and the pulse shaping filter(s).

Filtered multi-carrier communications

The disclosure relates to a radio transmitter device (and method) comprising a processor configured to: modulate a data frame onto a radio resource based on a transmission waveform, wherein the transmission waveform is formed according to a pulse shaping scheme; allocate a section of the radio resource for carrying information of the pulse shaping scheme; and transmit a signal waveform with selected pulse shaping scheme over the radio resource, wherein the signal waveform includes the information of the pulse shaping scheme and this information is sent over the allocated section of the radio resource. The disclosure further relates to a radio receiver device receiving such signal waveform.

The invention relates to a network entity for managing communications of a plurality of communication devices within a communication network, a communication device of the plurality of communication devices being configured to transmit a multi-carrier communication signal comprising a plurality of sub-carriers, and to transmit an energy efficiency indicator indicating an energy efficiency specification of the communication device, the network entity comprising a communication interface being configured to receive the energy efficiency indicator over the communication network, and a processor being configured to determine a sub-carrier frequency spacing of the plurality of sub-carriers upon the basis of the energy efficiency indicator, and to generate a resource block indicator associated with the communication device, wherein the resource block indicator indicates the sub-carrier frequency spacing, wherein the communication interface is further configured to transmit the resource block indicator over the communication network to the communication device.

Adaptation of subcarrier frequency spacing based on energy efficiency indicator

This application discloses a pulse shaping method, a transmitter, a receiver, and a system. The transmitter includes an inverse Fourier transform module, a pulse shaping filter, a pulse shaping controller, and a parallel-to-serial conversion module. The pulse shaping controller is configured to: receive pulse configuration signaling, generate, based on the pulse configuration signaling, a pulse parameter corresponding to a to-be-configured pulse, and output the pulse parameter to the pulse shaping filter. The pulse shaping filter is configured to: perform subcarrier-level filtering on an output signal of the inverse Fourier transform module, perform pulse shaping processing on the output signal of the inverse Fourier transform module based on the pulse parameter, and output a processed signal in serial by using the P/S module. Different pulse parameters correspondingly represent different pulse shapes. In the foregoing solution, pulse shaping can be flexibly configured, to support different communication scenarios.

Pulse shaping method, transmitter, receiver, and system

The present invention is directed to a transmitter and receivers for filterbank multicarrier (FBMC) communication. The transmitter comprises a processor adapted to calculate two auxiliary pilot symbols, and a precoder adapted to insert the two calculated auxiliary pilot symbols into a symbol structure of symbols, the symbols adjacently surrounding a main pilot symbol, wherein the precoder is adapted to insert the two auxiliary pilot symbols at two symbol positions of the symbol structure, which are symmetric to the main pilot symbol P in a time domain and/or in a frequency domain.

Transmitter, receiver and system for filterbank multicarrier communication

The disclosure relates to a new Alamouti-based mapping scheme for use in a real field FBMC modulation system which can reduce FBMC-intrinsic interference and allows approaching optimal performance. The Alamouti-based mapping scheme proposed herein can be used for implementing space-time or space-frequency block codes (STBC/SFBC) codes. The proposed Alamouti-based mapping scheme suggests specific patterns to negate/invert signs of the modulation symbols of Alamouti pairs in the Alamouti mapping. By using these special patterns of sign negation, the FBMC-intrinsic interference can be reduced significantly so that it may become possible to use conventional Alamouti demapping/decoding procedures on the receiving side with an overall acceptable performance in real life systems.
