SIGNAL PROCESSING METHOD AND APPARATUS

摘要

The present invention discloses a signal processing method and apparatus, and pertains to the field of communications technologies. The apparatus includes: a processor and a memory. The method includes: setting each sampling point signal on an orthogonal frequency division multiplexing OFDM symbol, and obtaining an input signal; calculating a constraint matrix according to a frequency selective fading channel characteristic; and calculating an output signal according to the sampling point signal, the input signal, and the constraint matrix. The present invention resolves a problem that frequency selective fading has an impact on transmission of the OFDM symbol, and a constraint matrix obtained according to a flat fading channel characteristic is not applicable to the OFDM symbol, thereby achieving an effect of reducing the impact of the frequency selective fading on the transmission of the OFDM symbol.
