摘要： Disclosed is a wireless backhaul network for a communications system. The network comprises a congregate node connected to the communications system; a plurality of access points, each access point having associated amounts of incident bidirectional traffic to be conveyed to and from the congregate node; and a plurality of bidirectional wireless links adapted to convey the traffic between the access points and the congregate node. The congregate node is configured to allocate spectrum to each directional component of each link within a predetermined available spectrum for the conveyance of the traffic, wherein the allocation is dependent on the amounts of traffic at the respective access points.

摘要： Disclosed is a wireless communication system comprising a plurality of antennas, a plurality of base stations, each base station being adapted to connect to one or more of the antennas over an available spectrum, and a wireless switching module. The wireless switching module is adapted to allocate one or more portions of the available spectrum to each antenna dependent on a compatibility constraint on the antennas, and assign each antenna for connection to a base station.

摘要： Disclosed is a user terminal for wireless communication with a remote access point, the user terminal comprising: a mapping module adapted to map one or more input data bits to an uplink symbol; a delay module adapted to apply a delay to the uplink symbol; a transmit module adapted to modulate the delayed symbol into a frequency channel; and a directional antenna oriented along a dominant path to the access point, the antenna being adapted to transmit the modulated symbol to the access point, wherein the delay is chosen such that the transmitted symbol arrives at the access point simultaneously with a further symbol modulated into the frequency channel and transmitted by a further user terminal.

摘要： A digital communications apparatus for processing a data vector includes a transmitter for communicating with a receiver across a channel having channel characteristics. A transmit vector is computed from the data vector and from values defining a basis for a transmit lattice. The transmit lattice defines a set of transmit symbols of length N and is related to an orthogonal receive lattice by the channel characteristics. The computation is performed according to an algorithm of order N complexity.

摘要： A user terminal for wireless communication with a remote access point can include a mapping module, a delay module, a transmit module, and a directional antenna. The mapping module can be used to map one or more input data bits to an uplink symbol. The delay module can be used to apply a delay to the uplink symbol. The transmit module can be used to modulate the delayed symbol into a frequency channel. The directional antenna can be oriented along a dominant path to the access point, and the antenna is used to transmit the modulated symbol to the access point. The delay is chosen such that the transmitted symbol arrives at the access point simultaneously with a another symbol that is modulated into the frequency channel and transmitted by another user terminal.
