英文摘要 | Channel estimation for the millimeter wave (mm-wave) MIMO systems with hybrid precoding can be performed by estimating the path directions of the channel and corresponding path gains. Researchers often apply the multiple signal classification (MUSIC) method to estimate angle of arrivals (AoAs) and angle of departures (AoDs), however their schemes are all based on the communication systems equipped with uniform linear arrays (ULAs), which means that only azimuth angle is considered and we cannot get more accurate channel state information (CSI). Different from the previous work, this paper does not ignore the effection of the elevation parameters by proposing a two-dimensional (2-d) channel estimation scheme in the systems with L-shape arrays and uniform planar arrays (UPAs). The simulation results show that the proposed channel estimation scheme can achieve higher accuracy in the two types of arrays, thus obtaining more comprehensive channel information than conventional solutions. |
