1. A wireless communication system, comprising:

  • a communication link having a first end and a second end that communicate over reciprocal radio frequency channels, the communication link having a plurality of radios at the first end of the communication link and a combining radio at the second end of the communication link, each radio having a transmit beamformer, a receive beamformer and an adaptive antenna array having a plurality of antennas, each antenna communicating a beam and the plurality of beams of the plurality of antennas are adaptively combined and communicated over the communication link;

    each of the radios at the first end of the communication link that is capable of computing a receive beamform weight, estimating a signal to noise ratio for a data stream, forming transmit beamform weights based on the receive beamform weight and communicating the estimated signal to noise ratio for the data stream over the communication link using the formed transmit beamform weights and the adaptive antenna array to the combining radio at the second end of the communication link; and

    the combining radio that is capable of simultaneously computing a receive beamform weight for each radio at the first end of the communication link based on the data communicated from each radio at the first end of the communication link, estimating a signal to noise ratio for the data communicated from each radio at the first end of the communication link, forming transmit beamform weights based on the simultaneous receive beamform weights and communicating the estimated signal to noise ratio for the communicated data over the communication link using the formed transmit beamform weights and the adaptive antenna array back to each radio at the first end of the communication link to optimize and equalize the transmission of data over the communication link.
