  • Patent number: 9832062
    Abstract: An IS-OFDM system for point-to-point wireless communications that suppresses narrow-band interference comprises an IS-OFDM transmitter and an IS-OFDM receiver, wherein a transmitted signal comprises a plurality of subcarriers, and further wherein each subcarrier contains more than one and potentially all symbols transmitted in a given frame. The IS-OFDM transmitted signal is at a data rate that is equal to the data rate of the input data stream via the use of P/S converters.

  • Patent number: 9525529
    Abstract: An IS-OFDM system for ultra-wideband (UWB) wireless communications that suppresses narrow-band interference, comprising an in-premises base station (IBS) is described. The IBS further comprises an IS-OFDM transceiver for communicating with a plurality of in-premises terminals (ITs) without creating interference outside an in-premises perimeter. Further, a method for operating an IS-OFDM system for ultra-wideband (UWB) wireless communications that suppresses narrow-band interference and provides local area networking services, in-premises distribution of broadcast cable channels and in-premises wireless access and routing to external networks is described, without creating interference outside an in-premises perimeter.

  • Patent number: 8908669
    Abstract: 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.

  • Patent number: 8532067
    Abstract: 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.
