Abstract
In this paper, a SDR model-based concept approach to the implementation of SDR digital communication. The wireless communication systems are a popular prototyping platform. We propose to create a secure, private wireless channel between two SDR (Software Defined Radio) terminals. It is not the safest option to transfer sensitive data wirelessly via the web. We, therefore, offer an alternative short distance use of the internet for the transmission of secured data. We have implemented different modulation and encoding methods and we have compared their performance with Matlab with the main aim of reducing the BER bit error rate. An entire digital communication system is installed and validated via on-air demonstration that includes a transmitter with an encoder and a receiver. For hardware efficiency, synchronization algorithms including offset stage, offset carrier frequency and recovery time are also optimized.
