摘要：

For multipath channel, an improved low-dimensional MUSIC delay estimation algorithm is proposed based on the OFDM symbol sequence and it constructs a new delay estimation spectral function to reduce the impact of spatial expansion. Simulation results show that the proposed algorithm performances much better than the traditional MUSIC algorithm at low SNR. Compared with the traditional MUSIC algorithm, this algorithm does not need to know the number of multipath and the time resolution is improved. Additionally, the computational complexity is also reduced, making this algorithm suitable for the case of mobile terminals with low power consumption. Copyright © 2014 Binary Information Press.
