Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0037] The present application discloses a method for generating a CS local oscillator sequence, so as to simplify the process of adjusting the CS local oscillator sequence.

[0038] In a communication system based on compressed sensing technology, the process of the transmitter compressing the spectrum of the original signal (for example, a sparse signal) is equivalent to the process of calculating the product of Z and C, and the process of the receiver recovering the signal is equi...

Abstract

Disclosed is a CS local sequence generation method. The method comprises: determining an initial value of a CS local sequence, wherein the initial value of the CS local sequence comprises N parameter sets, one of the parameter sets comprises a frequency, and the amplitude and phase of the CS local sequence at the frequency, and N is an integer greater than 1; performing digital processing on the N parameter sets to obtain N parameter control codes; using the N parameter control codes to generate a CS local sequence, wherein the CS local sequence is formed by overlapping N single-tone local signals, and one single-tone local signal corresponds to one parameter control code. The CS local sequence generation method disclosed in the present application simplifies the process of adjusting a CS local sequence and also makes the operation of adjusting a CS local sequence more flexible. Also disclosed are a CS local sequence generation device, a transmitter and a receiver.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a CS local oscillator sequence generation method, device, transmitter and receiver. Background technique [0002] Compressed sensing (CS, Compressed sensing) is a signal acquisition and encoding and decoding theory that utilizes signal sparsity or compressibility. The theory shows that when the signal is sparse or compressible, the reconstruction of the signal can be realized by collecting a small number of signal projection values ​​under the condition of much smaller than the Nyquist (Nyquist) sampling rate. At present, compressive sensing technology has been applied in the field of communication. [0003] In the communication system based on compressed sensing technology, the transmitter uses the CS local oscillator sequence to compress the spectrum of the original signal, and the receiver uses the CS local oscillator sequence to restore the signal....
