Question

____ is a method used for calculating beamforming weights.

a.

Sample matrix inversion

b.

Indirect matrix inversion

c.

Convolution

d.

Correlation

Answer: (a).Sample matrix inversion Explanation:Sample matrix inversion or direct matrix inversion is a method used for calculating beamforming weights based on a known training sequence of length L. Adaptive algorithms iterate the weights in accordance to the received training sequence. A final estimate is obtained at the end of the training sequence.
