Results of Challenge 3: the true DOA (blue) and the DOA estimated by rectangular windowing (red) as a function of time. CHALLENGE 8.3. The results are shown in Figure 8.1. The average error in the angle estimate is 0 . 62 degrees, and the average relative error is 0 . 046. The estimated DOAs are quite reliable except when the signals get very close. CHALLENGE 8.4.

Unformatted text preview: new = f X x f X x = f 2 XX + xx . The matrix XX has 4 m 2 entries, so multiplying it by f 2 requires O ( m 2 ) mul-tiplications. The number of multiplications needed to form xx is also O ( m 2 ) multiplications. CHALLENGE 8.5. The results are shown in Figure 8.2. The average error in the angle estimate is 0 . 62 degrees, and the average relative error is 0 . 046. The results are quite similar to those for rectangular windowing....
