DOA Estimation with Spatial Spread Vector-Sensor Array Based on Biquaternion MUSIC

Table 1

Summary of the proposed method.

Step 1: encode the received data to and construct vector
Step 2: calculate the covariance matrix and perform biquaternion-valued EVD
Step 3: construct projector based on
Step 4: estimate the DOAs through 2-D peak searching in Eqs. (29) and (30)
