Abstract:
A communication device and a method for Orthogonal Frequency Division Multiplexing (OFDM) configured to receive a signal from a second device; perform a channel estimation on the signal, wherein the channel estimation comprises determining a channel path gain, a channel path delay, and at least one of a channel path angle of arrival (AoA) or a channel path angle of departure (AoD); determine an optimal analog beamforming direction based on the channel estimation; and communicating the data using the analog beamforming.

Claim (Index 9):
The device of  claim 8 , the baseband modem being further configured to determine the analog beamforming direction by the following equation: u = argmax u \ue89e P \ue89e \u2211 m = 1 l \ue89e G m \ue89e sin 2 \ue8a0 ( N \ue8a0 ( \u03b8 m - u ) 2 ) sin 2 \ue8a0 ( \u03b8 m - u 2 ) 1 + P \ue89e \u2211 j = l + 1 M \ue89e G j \ue89e sin 2 \ue8a0 ( N \ue8a0 ( \u03b8 j - u ) 2 ) sin 2 \ue8a0 ( \u03b8 j - u 2 ) where u is the analog beamforming direction; P is a transmit power per each sub-carrier; G m  and G j  is a channel gain for the mth and a jth path, respectively; N is a number of antenna elements; \u03b8 m  and \u03b8 j  is an AoA or the AoD for the mth and jth paths, respectively; and M is a number of channel paths.
