Abstract:
A repeater for a wireless communication network includes a first reception antenna for receiving a reception signal on a first path from one of an access point, another repeater or a wireless station device; a second reception antenna for receiving the reception signal on a second path; a reception weighting circuit for applying first and second weights to the reception signal to generate a first weighted reception signal and a second weighted reception signal; a signal combiner for combining the first and second weighted reception signals according to various mathematical combinations to generate a plurality of combined reception signals; and a transmission antenna for transmitting a transmission signal corresponding to one of the combined reception signals to one of the access point, the another repeater or the wireless station device.
