Исследование приемников систем SDR

Abstract

Данная работа посвящена исследованию SDR устройств и принципа их работы. Целью работы является исследование возможности реализации собственного SDR-приемника, сконструированного при помощи Arduino, а также рассмотрение характеристик и преимуществ полученного устройства. Путем тщательного наблюдения за прохождением сигнала приемников систем SDR от поступления на антенну до выхода из цифрового устройства обработки сигнала, был изучен принцип программно-определяемого радио и особенности в сравнении с традиционными радиоприемники супергетеродинного типа. В результате была предложена архитектура КВ приемника системы SDR, рассмотрены способности предложенного решения.

The given work is devoted to the study of SDR devices and the principle of their work. The aim of the work is to study the feasibility of implementing your own SDR receiver designed using Arduino, as well as to consider the characteristics and advantages of the resulting device. By carefully monitoring the signal path of the receivers of the SDR systems from entering the antenna to leaving the digital signal processing device, we studied the principle of software- defined radio and features in comparison with traditional superheterodyne type radios. As a result, the HF receiver architecture of the SDR system was proposed, and the capabilities of the proposed solution were considered.
