说明：  . Types of Beamforing Algorithm: The algorithm of the adaptive antenna is classified based on whether training signal is used and not used[1]. It is classified as blind and non-blind algorithm[2]. B. Non-Blind Algorithm: In this algorithm, the training signal is known to both transmitter and receiver the receiver received it transmitter during training period[3] with the training signal the beam former in the receiver can calculate the optimal weight vector.
