Design and Analysis of a Multiple and Wide Nulling Collaborative Beamforming Scheme in the Domain of 3-Dimensional Wireless Sensor Networks

Table 10

Null width (in degrees) corresponding to null steering using 20, 15, 10, and 5 nodes. The null width has been measured at the −20 dB power level in the average array factor.
