Title:
SIGNAL PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/135340
Kind Code:
A1
Abstract:
A signal processing method and a device are disclosed in the present invention, and relate to the technical field of communications. The device comprises a processor and a storage. The method comprises: setting each of the sampling point signals of an Orthogonal Frequency Division Multiplexing (OFDM) symbol and obtaining an input signal; calculating a constraint matrix according to the characteristic of a frequency selective fading channel; and calculating an output signal according to the sampling point signal, the input signal and the constraint matrix. The present invention solves a problem that the constraint matrix obtained according to the characteristic of a flat-fading channel is not applicable to the OFDM symbol due to that the OFDM symbol transmission is impacted by the frequency selective fading, and achieves an effect of reducing the impact on the OFDM symbol transmission caused by the frequency selective fading.
