Performance Evaluation of 2X2 MIMO Reconfigurable Testbed Communication System

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.
