The invention provides a link transmission time delay generation method with a configurable bit error rate, a link transmission time delay generation device and a link transmission time delay generation system. The link transmission time delay generation method comprises the steps of acquiring a configured time delay data frame parameter and a bit error rate data frame parameter; receiving to-be-processed data which are transmitted by an upper computer; writing the to-be-processed data into a memory according to writing speed of the to-be-processed data into the memory, monitoring the size of the to-be-processed data which are written into the memory, when the size of the to-be-processed data which are written into the memory is equal with the size of the data that correspond with the time delay data frame parameter, writing the to-be-processed data according to the writing speed of the to-be-processed data into the memory, thereby obtaining data after time delay processing; performing bit error processing on the data after time delay process according to the bit error rate data frame parameter, thereby acquiring data after bit error processing; and transmitting the data after bit error processing to a lower computer. The link transmission time delay generation method, the link transmission time delay generation device and the link transmission time delay generation system can realize link simulation for satellite network and deep space communication.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method, device and system for generating link transmission delay with configurable bit error rate. Background technique [0002] Satellite communication is a combination of aerospace technology and communication technology, and is an advanced communication method controlled by computers. It is a special form of microwave communication developed on the basis of microwave communication. Satellite communication refers to the use of artificial earth satellites as relay stations high above the ground to forward radio signals between two or more earth stations, thereby realizing the communication method of information exchange and information transmission between them. Because satellite communication has the advantages of large coverage, wide frequency bandwidth, large capacity, applicable to various services, and stable and reliable performanc...
