    摘要： In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.

    摘要： A method and system for beamforming communication in high throughput wireless communications. Analog beamforming involves constructing analog beamforming coefficients for beamforming communication on a wireless channel. Constructing analog beamforming coefficients includes selecting a signal tap from a multi-tap wireless channel for beamforming communication, wherein the selected signal tap has a higher signal quality relative to other signals taps, and determining beamforming coefficients for the selected tap by iterative acquisition of the coefficients based on power iteration.

    摘要： A beamforming method is disclosed that includes performing sequential beam transmissions in multiple directions and receiving replies to the transmissions (i.e. a sector search). The received transmissions can include information or channel parameters such as direction of arrival, signal to noise ratio, signal strength, etc., for each sector. Utilizing the parameters transmitted or fed back by the receiver, the transmitter can store control vectors that dictate a beam that can be utilized to commence a beam refinement procedure. In addition, the parameters can be utilized to select and implement a custom sequence to refine the communication channel between the device and the controller. The custom sequence can significantly reduce the time required to create a channel with acceptable qualities such that efficient high speed network communications can be conducted. Other embodiments are also disclosed.
