Embodiment Construction

[0075] An aviation digital communication simulation system of the present invention includes a digital baseband transmission system and a digital bandpass system; the digital baseband transmission system includes a basic coding module, an intersymbol-free module, and an eye diagram module; the digital bandpass system includes 2ASK modulation module, 2FSK modulation module, 2PSK modulation module;

[0076] The basic encoding module is used for encoding design of unipolar return-to-zero code, unipolar non-return-to-zero code, bipolar return-to-zero code, bipolar non-return-to-zero code, AMI code, and HDB3 code, and simulates corresponding to the encoded waveform. The basic coding module uses the rand function to randomly generate a random sequence, and uses the round function to round off the value, and then uses the for loop to read the random sequence, write a unipolar or bipolar return-to-zero code, and set each interval period as t 0 , use the for loop to judge the random s...

Description

technical field [0001] The invention relates to the technical field of civil aviation, in particular to an aviation digital communication simulation system and a simulation method thereof. Background technique [0002] The communication system is one of the important components of the civil aircraft avionics system, and it is also one of the key training basic courses for the avionics system design company. The training on the principles of the communication system has theoretical abstraction, complex mathematical operation derivation, rigid training courseware, manual drawing of waveform diagrams, and practical training. Strong operability and frequent emergence of new theories and concepts lead to boring and difficult to understand training, and the effect of new employee induction training is greatly reduced, making it difficult to carry out follow-up communication system design projects. [0003] The current training on the principles of communication systems in the avia...
