IMITATION EQUIPMENT FOR TESTING OF RECEIVING EQUIPMENT OF COMMUNICATION LINES WITH FREQUENCY, TIME AND CODE DIVISION OF CHANNELS Russian patent published in 2010 - IPC G05B17/02 G06G7/02 

FIELD: radio engineering.

SUBSTANCE: imitation equipment comprises serially connected noise-resistant (NR) coder, modulator, summator, converter, attenuator, and also noise generator and generator of pseudorandom sequence, outputs of which are connected to the second and third inputs of summator accordingly, personal computer, which comprises module of buffer accumulation with input-output high-speed device (IOHSD) and block of software. IOHSD output is connected to input of NR coder, and outputs of NR coder, modulator, summator and attenuator via controlled article are connected to the second inputs of IOHSD by the third inputs of IOHSD, which are inputs of outer signal from other devices, including actual signal.

EFFECT: expansion of functional capabilities of imitation equipment for provision of tuning, testing and assessing quality of receiving equipment functioning with types of access - multiple access with frequency division, time division and code division, reduction of its cost.
