Abstract

The invention discloses a frequency hopping control method, emission equipment and receiving equipment. During a communication process, interference frequency point detection is performed on a received signal through using a mode of combining correlation peak detection and error rate detection. On one hand, through a correlation peak detection mode, a misjudgement rate of an interference frequency point detection result is reduced; on the other hand, through an error rate detection mode, a misjudgement result during the correlation peak detection can be eliminated. Therefore, technical effects of effectively reducing a misjudgement rate of interference frequency point determination and increasing frequency hopping control communication quality are possessed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a frequency hopping control azimuth, a transmitting device and a receiving device. Background technique [0002] Frequency adaptive frequency hopping technology refers to the real-time or regular elimination of frequency points in the frequency set that are interfered or with poor channel conditions according to the results of channel quality evaluation, and at the same time remove the frequency points outside the frequency set with good channel quality and no interference The frequency point is added to the frequency set, and the frequency hopping communication technology is controlled to perform frequency hopping on the frequency set. This technology has the advantages of strong anti-interference and fading ability, high communication signal quality, and low bit error rate. [0003] However, the traditional frequency adaptive frequency hopping technology usually detects th...
