Implementation of the communication chain for education

摘要

The aim of this article is to show a realization of the communication chain using a digital modulation. The whole communication chain concludes knowledge gained during the studies at our department of electrical engineering. It is mainly an application of programming, embedded systems programming, a digital modulation / a demodulation as a part of a digital signal processing, network communications and others. The paper is primarily focused on the application a modulator and a demodulator implemented into a FPGA (Field Programmable Gate Array) chip. The identification of synchronization sequence using NXOR (not exclusive logical disjunction) instead of Cross Correlation Function is introduced. Data transfer of three-dimensional data matrix is realized and Bit Error Rate is presented.
