Abstract

The embodiments of the invention provide a method and a device for processing communication signals in a communication system. The method comprises the following steps: performing discrete Fourier transform DFT on input data to get a DFT data sequence; and performing orthogonal frequency division multiplexing on the DFT data sequence and a pilot frequency sequence in the same symbol. By implementing the embodiments, the peak-to-average power ratio of information transmission in a communication system and the transmission cost of pilot frequency can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and device for processing communication signals in a communication system. Background technique [0002] In wideband communication systems, in order to combat frequency-domain selective fading caused by multipath, the entire system bandwidth is generally divided into multiple sub-bands, and each sub-band can be considered as flat fading, so that the receiver can use a simple linear frequency domain equalizer. Frequency domain equalization, and achieve high receiving performance. A system that divides a broadband signal into multiple narrowband signals in the frequency domain for transmission and reception is called a multi-carrier system. An Orthogonal Frequency Division Multiple Access ("OFDMA" for short) system is a typical multi-carrier system. Although the multi-carrier system reduces the complexity of the equalization performed by the receiv...
