Embodiment 1

[0051] refer to figure 1 , which shows an interactive schematic diagram of a collision signal recognition provided in Embodiment 1 of the present invention. In this embodiment, the method includes:

[0052] S101: During the process of generating a signal frame, the transmitter maps preamble information and padding information to a first constellation point, and maps useful information to a second constellation point; the first constellation point and the second constellation point are different;

[0053]In the field of digital communication, digital signals are often represented on the complex plane to intuitively represent the relationship between signals. This diagram is a constellation diagram. In this embodiment, the preamble information and the filling information are mapped to the same constellation point, and the useful information is mapped to a constellation point different from the preamble information and the filling information. Wherein, the preamble information a...

Embodiment approach 1

[0056] mapping the preamble information and padding information to a first constellation point in the fifth constellation point set, and mapping the useful information to a second constellation point in the fifth constellation point set; the first constellation point and the second constellation point Constellation points are different;

[0057] For example: the fifth constellation point set contains multiple constellation points, for example: S={+1, +j} If the preamble information is mapped to +j, the useful information is mapped to +1.

Embodiment approach 2

[0059] mapping the preamble information and the padding information to the first constellation point in the third constellation point set;

[0060] mapping the useful information to a second constellation point in the fourth constellation point set;

[0061] The third constellation point set and the fourth constellation point set contain different constellation points.

[0062] Based on the second embodiment above, the third constellation point and the fourth constellation point need to be constructed in advance, wherein the constructed third constellation point set and the fourth constellation point set contain different constellation points.

[0063] For example: Suppose the third constellation point set is St, the fourth constellation point set is Sy, the third constellation point set St, and the fourth constellation point set Sy meet the following conditions:

[0064] S y ∩S t = φ;

[0065] For example, suppose the third set of constellation points is S t ={+j,-j}, th...

Abstract

The invention discloses a collision signal identification method and system, and the method comprises the steps: mapping preamble information and filling information into a first constellation and mapping useful information into a second constellation in the process of generating a signal frame, transmitting the generated signal frame to a receiver through a wireless channel, and the receiver obtains the baseband signal waveform corresponding to the leading information from the signal frame, calculates the preset index information of the overlapped signal at the target position in the signal frame, and determines whether the overlapped signal at the target position of the signal frame contains useful information according to the relationship between the preset index information and the reference value. Therefore, the preamble information and the filling information are mapped into the same constellation point, so that the preamble information and the filling information have the same characteristics, the preset index information of the baseband signal waveform corresponding to the preamble information is used as the reference value to identify the information of the target position on the signal frame, and the accuracy of useful information identification is improved.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a collision signal identification method and system. Background technique [0002] Cellular mobile communication develops most rapidly in the field of communication. The cellular mobile communication system has experienced five generations of evolution. The channel multiple access technology adopted has experienced the replacement from FDMA, TDMA, CDMA to OFDMA. Multiple access technology refers to the realization of multi-user Among them, the intra-frame multiplexing technology is a multiple access technology that uses useful information to appear at different positions in the frame to represent the channel occupancy of different users through the design of the frame structure. [0003] For intra-frame multiplexing technology, for example, the transmission time shared by multiple users is divided into shared and exclusive parts, in which each user transmits the same field in the...
