Problems solved by technology

However, in the traditional technology, the detection of effective information cannot be carried out together with the detection of communication parameters; the traditional technology needs to wait until the detection of communication parameters before judging that the information is meaningless based on the information obtained by frequency domain conversion, demapping and decoding information
It can be seen that the traditional technology cannot quickly judge whether the communication signal is valid

Embodiment Construction

[0046] Please refer to figure 1 , which shows the timing of a signal x(n). The signal x(n) may be a communication signal, such as a baseband communication signal in the receiving end in a wireless communication system. Signal x(n) has multiple sequentially arranged segments, figure 1 The sections CP[j-1], D[j-1], CP[j], D[j], CP[j+1] and D[j+1] are represented as representatives. Among them, segments D[j-1], D[j] and D[j+1] are information segments, which carry information to be transmitted by the transmitter; and segments D[j-1], The sections CP[j-1], CP[j] and CP[j+1] before D[j] and D[j+1] are the cyclic message sections, that is, the cyclic messages of the information section prefix (cyclic prefix), corresponding to the sections D[j-1], D[j] and D[j+1] respectively. Each cyclic message segment CP[j] is arranged alternately with each information segment D[j]; that is, the information segment D[j] is arranged between two adjacent cyclic message segments CP[j] and CP[j+ ...

Abstract

The invention provides a method of communication parameter detection and a related device. The method and the related device are used for detecting the length of protection time intervals of message loops in communication signals. The method includes the steps of searching peak values in self-relevant signals of the communication signals, providing the peak values for the message loops, classifying time difference between the two adjacent peak values into one of a plurality of intervals of histogram statistics, deciding the length of the protection time intervals according to results of the histogram statistics, finding a peak value, providing a signal average according to an average in average value statistics of the self-relevant signals, comparing a ratio between the peak values and the signal average, and judging whether the ratio is larger than a critical value. Accordingly, whether effective information is carried in the communication signals can be detected.

Description

technical field [0001] The present invention relates to a communication parameter detection method and a related device, and in particular to a communication parameter detection method and a related device which can detect the length of a protection period based on histogram statistics and detect whether a communication signal carries valid information. Background technique [0002] In the modern information society, various communication systems have been widely used, especially wireless communication systems, such as wireless communication systems based on Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) technology. For example, the wireless area network standard of IEEE 802.11a, the wireless metropolitan network standard of IEEE 802.16, and the wireless digital video broadcasting (DVB, Digital Video Broadcasting) standard developed in Europe all adopt OFDM technology. [0003] In an OFDM wireless communication system, when the ...
