Abstract:
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.

Claim (Index 2):
The method according to  claim 1 , wherein when a first flag bit Flag head  is equal to a first enable value, to perform pulse shaping processing on the communication signal based on the pulse parameter, the processor is configured to:\n add a cyclic prefix of a first length to an orthogonal frequency division multiplexing (OFDM) symbol corresponding to the communication signal; for a header part of the OFDM symbol with the added cyclic prefix of the first length, perform windowing processing on the OFDM symbol at M sampling points of the header part by using a former part of a preset windowing function, wherein M is a positive integer; add X sampling points of a tail part of a previous OFDM symbol and the OFDM symbol at X sampling points of a header part of the OFDM symbol obtained after the windowing processing, wherein X is a positive integer; and perform parallel-to-serial conversion on a plurality of channels of signals corresponding to the OFDM symbol obtained after the adding, and output, via the transceiver, a converted signal.
