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 15):
The method according to  claim 13 , wherein when a second flag bit Flag tail  is equal to a second enable value, performing pulse shaping processing on the communication signal based on the pulse parameter comprises:\n adding a cyclic suffix of a second length to an orthogonal frequency division multiplexing (OFDM) symbol corresponding to the communication signal; for a tail part of the OFDM symbol with the added cyclic suffix of the second length, performing windowing processing on the OFDM symbol at N sampling points of the tail part by using a latter part of the preset windowing function, wherein N is a positive integer; and storing, in a storage medium, Y sampling points of a tail part of the OFDM symbol obtained after the windowing processing, wherein Y is a positive integer.
