RADIO CHANNEL IMITATOR Russian patent published in 2019 - IPC H04B17/391 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the field of radio engineering and can be used for testing receiving and transmitting devices and modeling a radio channel. Radio channel simulator contains, among other things, noise-like signal driver (NSD) (5), p fixed attenuators (15), t second switches (12), t third adders connected in adders (13) and t second splitters (14), outputs which are connected to the inputs of the corresponding output controlled attenuators (9.1–9.k), while the other inputs t of third adders (13) are connected to the corresponding outputs of the first splitter (8), the other outputs t of second switches (12) are connected to the corresponding inputs of second adder (7), and the inputs t of second keys (12) are connected to the outputs of DAC (6) from the second to s, respectively, however, the outputs of DAC (6) from the first to the p are connected to the inputs of p fixed attenuators (15), respectively. In addition, input control inputs (1.1…1.N) and outputs (9.1…9.k) controlled attenuators, first (10) and second (12.1…12.t) keys, as well as NSD (5) are connected to the control bus.

EFFECT: expanding the functionality of the simulator by creating a variety of environmental conditions during the propagation of the radio signal.
