Patent number: 9585114Abstract: Disclosed is a user terminal for wireless communication with a remote access point. The user terminal may include 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 an antenna being adapted to transmit the modulated symbol to the access point. The delay can be 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.Type: GrantFiled: November 5, 2015Date of Patent: February 28, 2017Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Hajime Suzuki, Douglas Brian Hayman, Joseph Abraham Pathikulangara, Iain Bruce Collings, Zhuo Chen

Patent number: 9007900Abstract: 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.Type: GrantFiled: June 30, 2011Date of Patent: April 14, 2015Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Iain Bruce Collings, Wei Ni

Patent number: 8675512Abstract: 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.Type: GrantFiled: August 10, 2009Date of Patent: March 18, 2014Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Hajime Suzuki, Douglas Brian Hayman, Joseph Abraham Pathikulangara, Iain Bruce Collings, Zhuo Chen

Patent number: 7876838Abstract: 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.Type: GrantFiled: June 17, 2004Date of Patent: January 25, 2011Inventors: Ian Vaughan Lyndon Clarkson, Iain Bruce Collings
