Abstract. In order to solve the problem of low spatial resolution caused by signal correlation for angle estimation，a novel DOA measurement approach for related signal is proposed based on vehicle MIMO-OFDM signal. The proposed method uses the cross-correlation matrix to reconstruct the signal covariance matrix, which can simultaneously estimate the DOAs of relevant and irrelevant signals. Simulation results indicate that the proposed method provides higher resolution performance for coherent sources compared to spatial smoothing algorithms ,and the computational complexity is also reduced to some extent.

“…Since the concept of intelligent transportation systems (ITS) is put forward, research for Internet of Vehicles (IOV) [1][2] has become more widely. As a key research area of ITS, IOV system can not only realize Vehicles-to-vehicles(VTV) and road-to-vehicles(RTV) communciation,but also have the ability of radar sensing.…”
