Abstract: A single-carrier-modulation communication system for transmitting data over a wireless link, the communication system including, on a first side of a wireless link one single-carrier-modulation receiver associated with a single antenna, on a second side of the wireless link a plurality of antennas and a plurality of single-carrier-modulation transmitters, each one of the plurality of transmitters associated with one of the plurality of antennas, the transmitters each further associated with a pre-coding filter, and the plurality of transmitters are arranged to each transmit same data via a respectively associated pre-coding filter and the associated antenna, using the pre-coding filters to perform beam-forming to the one receiver. Related apparatus and methods are also described.

Abstract: A method for managing transmission settings in a wireless point-to-point link, including making a first estimate of a current required traffic capacity for transmitting in a first direction, from a first point in the wireless point-to-point link to a second point, and selecting a first technique for transmitting in the first direction, based, at least in part, on the first estimate of the current required traffic capacity, in which the first technique selected provides a traffic capacity which is less than a maximum capacity possible in the first direction. Related apparatus and methods are also described.

Abstract: A method of communicating bi-directionally over a wireless communication system including sending data from a first location, from a first antenna, over a first plurality of signals at different frequencies, to a second plurality of spatially separated antennas at a second location, each of the second plurality of spatially separated antennas feeding a corresponding transmitter/receiver of a plurality of transmitter/receivers at the second location. A method of communicating over a wireless communication system including transmitting same data from a first location, using each one of a plurality of Adaptive Coding and Modulation (ACM) signals at different frequencies, to receivers corresponding to each one of the frequencies at a second location, receiving the transmitted signals, and combining the received signals. Related apparatus and methods are also described.
