Abstract
Recently, MIMO-OFDM Is widely used In wireless communication standards. In several cases, it utilizes higher-order modulation technique to increase transmission rate, but on the other hand it leads to being more susceptible to bit error. In this paper, we conducted 2×2-MIMO-OFDM implementation and performed a field experiment to evaluate the performance of MIMO-OFDM with 16-QAM, 64-QAM, and 256-QAM technique. The experiment was conducted in a real environment using USRP N210 hardware devices as the SDR platform. The result has provided a empirical reference that the transmission performance which is bit error rate (BER) was highly influenced by SNR level and modulation technique. It this experiment, the performance of 2×2-MIMO-OFDM spatial diversity with STBC algorithm in LOS was better than the one in NLOS environment.
