Abstract
A computer-implemented method for calculating interference reducing parameters for cancelling wireless signal interference within a data communication network, comprising: per each of a plurality of antennas of a multi-sector hub communicating with a data communication network and with a corresponding transceiver of a plurality of distant transceivers: calculating a plurality of calibration factors based on values extracted from sequential transmission and reception of predetermined signals between each of the plurality of antennas of the multi-sector hub; calculating at least one receive interference cancellation parameter, to isolate desired signals transmitted by the corresponding distant transceiver from the undesired interference signals transmitted by other non-corresponding distant transceivers; calculating at least one transmit interference parameter for each non-corresponding antenna of the hub, based on the calculated receive interference cancellation parameters and the calibration factors; and generating the interference parameters for applying during operation of the multi-sector hub to generate interference cancellation signals.
