Performance Evaluation of 2X2 MIMO Reconfigurable Testbed Communication System

Abstract

The main reason for shifting to 5G is to handle the increasing data traffic demands, by using reconfigurable testbed systems in a real-world deployment scenario. Due to advancement in embedded technology cheaper, smaller, lighter and more flexible devices are available in the market, one among them is USRP. In this research work, a 2X2 MIMO-QAM system is simulated, implemented and comparative analysis is done using the SDR test-bed. Further, this paper extends to a 2X2 MIMO-OFDM system and the best sequence for training is obtained based on various parameters such as SNR(dB); BER; delay(µ sec); Error Statistics; Estimated Offset for different training sequences.
