Abstract

Embodiments of the invention disclose a signal processing method and a wireless signal sending and receiving device. The method comprises the following advantages: modulating a baseband signal to be transmitted to at least one sub-carrier; determining a baseband shaping filter parameter and a spectrum expansion coefficient for the at least one sub-carrier which is provided with the baseband signal to be transmitted through modulation; carrying out time-domain and frequency-domain shifting of the baseband shaping filter parameter; filtering the at least one sub-carrier based on the shifted baseband shaping filter parameter to get a first modulated sub-carrier; expanding the spectrum of the first modulated sub-carrier based on the spectrum expansion coefficient to get a second modulated sub-carrier; and transmitting data based on the second modulated sub-carrier.

Description

technical field [0001] The invention relates to signal processing technology, in particular to a signal processing method and wireless signal transceiver equipment. Background technique [0002] The fifth-generation mobile communication system 5G has higher requirements for air interface technology, among which waveform technology is the basis of air interface technology. When the sub-frame data is transmitted through the GFDM waveform, there is non-orthogonality among the sub-carriers used when the sub-frame data is modulated, that is, there is carrier interference (ICI, Inter-Carrier Interference). Moreover, the transmission of data through GFDM will lead to high system processing complexity. How to reduce ICI and reduce processing complexity has become an urgent technical problem to be solved. Contents of the invention [0003] Embodiments of the present invention provide a signal processing method and a wireless signal transceiving device. [0004] The technical sch...
