Fig. 6From: Low-complexity DOA estimation from short data snapshots for ULA systems using the annihilating filter techniqueTracking error of both estimators with QPSK, K=2 sources, N=1, \( {\dot{\theta}}_1={\dot{\theta}}_2=1.17{5}^{{}^{\circ}} \)/sample, R=100, N a =16, and SNR =15 dBBack to article page
