Huaxiong Yao · Microelectronics & Computer · 2007
Based on summarizing MUSIC algorithm of direction finding,the author analyzes the proportion of every step to the whole run time of the implementation of MUSIC algorithm.It has been proved that peak values searching costs a majority of run time.Thus three kinds of peak values searching algorithms are brought out.According to the result of simulations and testings,the hardware architecture utilizing pipelining and interleaving parallel technologies is designed.At last,the accuracy of DOA estimation using two kinds constructing spatial spectrum is discussed.And the conclusions in this paper are verified by simulation experiments.
