Patent number: 8908669Abstract: Time division multiplexed input signals (i.e., separated into time slots) are spread in each time slot with a destination code. This spreading is applied for destination identification as opposed to signal information modulation. Each spreading signal is associated with a particular destination for a particular time slot. These spread signals are then combined on a code division bus. Output signals for retransmission to the destinations are recovered from the bus by application of despreading codes. Each despread signal has a destination code which appears in its individual time slot. In a variant code division multiplexed signals are directed to a destination by use of time slot interchanger to achieve time division switching to route the CDMA multiplexed channels.Type: GrantFiled: August 13, 2012Date of Patent: December 9, 2014Assignee: AT&T Intellectual Property II, L.P.Inventor: Diakoumis Parissis Gerakoulis

Patent number: 8532067Abstract: An access radio port is provided that spreads a payload data signal, extracted from an ATM packet, with a uniquely assigned orthogonal code, transmits the spread payload data signal to one of a group of mobile subscriber terminals located within a microport cell of a wireless terrestrial network, and releases the uniquely assigned orthogonal code. In another aspect, a mobile subscriber terminal, is located within a microport cell of a terrestrial wireless network that interfaces with an access radio port. The mobile subscriber terminal receives an assignment of a unique orthogonal code, spreads a payload data signal using the unique orthogonal code, modulates and forwards the spread payload data signal to the access radio port, and releases the assignment of the unique orthogonal code.Type: GrantFiled: March 23, 2011Date of Patent: September 10, 2013Assignee: AT&T Intellectual Property IL, L.P.Inventor: Diakoumis Parissis Gerakoulis
