基于NI USRP-RIO平台的MIMO-OFDM信道估计研究与实现
Research and implementation of MIMO-OFDM channel estimation based on NI USRP-RIO platform
摘要
Abstract
On the basis of universal software radio peripheral-compact reconfigurable input/output (USRP-RIO) platform made by National Instruments(NI),the physical layer of multiple input multiple output-orthogonal frequency division multiple-xing(MIMO-OFDM)radio frequency(RF)communication system was designed,the LabVIEW program related to channel esti-mation was compiled emphatically,and the performances of the classical frequency-domain least square(LS)channel estimation method and time-domain LS channel estimation method were analyzed and verified. The test data demonstrates that the bit error rate of time-domain LS channel estimation method is superior to that of the frequency-domain LS channel estimation method in the Rician fading channel environment based on logarithmic distance path loss model,which is consistent with the theoretical analysis. The validity of the system implementation was verified.关键词
