Abstract
An interference wave removing apparatus removing interference wave between angle diversity branches is disclosed. This apparatus is suitable for microwave communication beyond line-of-sight. The apparatus comprises a first reception unit for main beam, a second reception unit for angle beam, a first correlator for generating a first correlation signal corresponding to the first reception unit, a second correlator for generating a second correlation signal corresponding to the second reception unit, a first multiplier for multiplying an output of the first reception unit and the first correlation signal, a second multiplier for multiplying an output of the second reception unit and the second correlation signal, a subtractor for subtracting an output of the first multiplier from an output of the second multiplier, a channel quality compensator for compensating for an output of the subtractor for the channel quality, and a delay element for delaying an output of the channel quality compensator. The second reception unit can be adjusted a directivity for the angle beam and is controlled to follow up the angle beam in response to an output of the delay element.
