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 12):
The method according to  claim 7 , wherein:\n the pulse parameter comprises all or a part of a preset parameter set, and the preset parameter set comprises a first flag bit Flag head , a second flag bit Flag tail , a first value N 1 , a second value N 2 , a shape P type  of the to-be-configured pulse, and a length K of the to-be-configured pulse relative to a single symbol period; and the first flag bit Flag head  is used to indicate whether pulse shaping is performed on a symbol header, the second flag bit Flag tail  is used to indicate whether pulse shaping is performed on a symbol tail, the first value N 1  is used to indicate a quantity of sampling points that are in a single symbol, on which pulse shaping is to be performed, and whose magnitude weights are not equal to 1, and the second value N 2  is used to indicate a quantity of sampling points that are outside a single symbol and on which pulse shaping is to be performed.
