METHOD AND DEVICE FOR PROCESSING SIGNALS OF COMMUNICATION LINES ON BASIS OF SIGNAL MODEL AND REPROGRAMMABLE ELECTRIC CIRCUITS

摘要

FIELD: radio engineering, digital and computer engineering, possible use during receipt, demodulation and processing of signals of satellite and radio-relay communication lines.;SUBSTANCE: in accordance to the invention, signal is received, demodulated, transformed to digital form, model of signal being processed is synthesized, nomenclature and resource are selected for programmable logic devices (PLD), ROM, RAM, controllers, microprocessors, computer engineering devices, other reprogrammable or program-controlled electronic and radio devices, and a circuit of connections is created; aforementioned electronic and radio devices are configured in terms of executed functions in signal, loading module of signal being controlled is created, serviceability of resulting circuit is checked by modeling method or using real signal, in case of failure, local inoperative section of reprogrammable electronic and radio devices is determined and the circuit program is corrected, in case of success, program is recorded in a bank of electronic circuits, for each new signal aforementioned operations are repeated and a bank of loading modules is created to accommodate different signals, making it possible to automatically adjust to any signal on repeat thereof. To process any signal available in the bank of loading modules, it is sufficient to select required loading module and program electronic and radio devices. Two-channeled receiving and demodulating device contains serially connected radio-receiving device, analog-digital transformation block, a set of N-coherent digital demodulators, interference-resistant decoders, and also VME bus interface, controller and personal electronic computing machine. All devices with the exception of the personal electronic computing machine are integrated in euro-block type structure and are made on basis of reprogrammable or electronically controllable electro-radio products.;EFFECT: expanded functional capabilities.;2 cl, 2 dwg
