This work studies one of the methods of adapting data transmission process in data measuring systems, which involves manipulation of width of the data being transmitted depending on communication channel status. The research was conducted with the simulation model of data transmission system based on the binary symmetric channel with application of the Bose-Chaudhuri-Hocquenghem error correcting code. The basis for the suggested adaptive system is status assessment of the data transmission channel, according to which transmitted data width and parameters of error correcting code are selected providing a given error probability at the receiving end with consideration of the limited throughput capacity of the communication channel. In this case, should the status of the communication channel not allow data transmitting with the given reliability level, only high-order bits will be transmitted and while low-order bits are kept in a buffer memory for a further transmission. Assessment of the communication channel status is performed based on error-code decoding statistics at the receiving end with transmission of this statistics in any form to the transmitting side. Simulation results confirm accuracy of the suggested solution and enable assessment of the main parameters of the data transmission systems with the proposed adaptive method.
