The implementation of channel coding into the digital transmission chain consisting of VSG PXI-5670 - VSA PXI-5661

This article is focused on techniques for error detection and correction, which occur during a transmission in modern digital communication channels. The real implementation of these channel coding techniques into the digital communication system is presented in this article. The system is based on the PXI modular platform consisting of RF VSG PXI-5670 and RF VSA NI PXI-5661. The proposed communication system structure is based on a software-defined radio conception. Author’s goal was to describe and afterwards with real measuring, to revise properties of the measuring system based on this flexible approach. These systems seem to be very useful for testing of new generation transmission systems.
