Embodiment Construction

[0006] In the following, in combination with the technical scheme and the quantitative model used in practice, the specific implementation effect of the present invention will be described by taking a certain type of aircraft remote control command judgment in the shooting range test as an example.

[0007] The quantization model is the basic system of non-detection and error correction and non-large loop detection. The channel is a symmetrical channel, that is, the probability of error code "0" and "1" changes is equal, the instruction length is L=64, the practical code set N=8, and the practical code is the smallest Hamming distance d=8, analysis bit error rate Pe=0.5~1×10-7.

[0008] 1. Commonly used remote control command probability quantitative analysis method

[0009] In order to facilitate the understanding of the conclusions of the traditional "five judgments and three" criterion instruction probability and the improved "five judgments and three" criterion instruction...

Abstract

The invention discloses an improved 'five to three' method for remote control instruction bit-by-bit judgment, belongs to the technical field of aircraft measurement and control and relates to remote control instruction judgment criterion processing method, in particular to a bit-by-bit judgment method of remote control instructions. The method is characterized in that five received instructions are compared longitudinally bit by bit, the 'station' value is judged according to the majority, if three or more '1' exist, the 'station' is judged to be 1, on the contrary, the 'station' is judged to be 0, finally the judgment results of all 'stations' form the final received instruction, instruction is compared with a practical instruction set, and if the instruction is consistent with the practical instruction set, the instruction is detected out, or else, the process is given up. By means of the improved 'five to three' method for remote control instruction bit-by-bit judgment, the problem that the remote control instruction detection rate is low when a traditional 'five to three' criterion is adopted is solved, the overall performance index of a system is effectively improved, and instruction detection rate is raised by two or more levels.

Description

technical field [0001] The improved "five judgments and three" method for bit-by-bit judgment of remote control commands belongs to the technical field of aircraft measurement and control, and relates to the processing method of judgment criteria for remote control commands, especially the problem of using the bit-by-bit judgment method to process remote control commands. Background technique [0002] At present, the judgment criteria of remote control commands in the field of domestic measurement and control generally adopt the traditional command-by-command judgment, that is, the traditional judgment rule of "five judgments and three" for remote control commands that meet the requirements, called the "five judgments and three" rule. The basic process is: the system receives five instructions in a row, if there are more than three identical instructions, compare the instruction with the practical instruction set, if there is a match, check out the instruction, otherwise give...
