Patent number: 7054376Abstract: A facility transport system for transporting high speed Ethernet data over digital subscriber lines. The system, referred to as 100BaseS, is capable of transmitting 100 Mbps Ethernet over existing copper infrastructure up to distances of approximately 400 meters. The system achieves bit rates from 25 to 100 Mbps in increments of 25 Mbps with each 25 Mbps increment utilizing a separate copper wire pair. Each pair used provides a bidirectional 25 Mbps link with four copper wire pair connections providing 4×25 Mbps downstream channels and 4×25 Mbps upstream channels. The system utilizes framing circuitry to adapt the 100BaseT input data signal to up to four separate output signals. A DSL Ethernet Port card couples the modem to each twisted pair used. Each DSL Ethernet Port card comprises modem transmitter and receiver circuitry for sending and receiving 100BaseS signals onto twisted pair wires.Type: GrantFiled: May 27, 1999Date of Patent: May 30, 2006Assignee: Infineon Technologies AGInventors: Avinoam Rubinstain, Yackov Sfadya, Shimon Peleg, Noam Alroy, Amnon Harpak, Boaz Porat

Patent number: 6922436Abstract: Method and modem for fast timing recovery of transmitted data between a master ?DSL modem and a slave ?DSL modem, over a noisy, high loss, high distortion wiring. Transmitted QAM symbols are received and sampled at the slave modem. The sampled data is split into in-phase and quadrature channel, each of which is filtered by matched filter. The filtered outputs are sampled at twice the symbol rate and the lower and upper band edge components are extracted by modulating each of the sampled sequences of outputs with two discrete time sequences: cos(0.5 ? n)=. . . 1,0,?1,0 . . . and sin(0.5 ? n)=. . . 0,1,0,?1 . . . . Each of the resulting products is filtered with a first order low-pass filters and re-sampled again at the symbol rate. The Bit Error Rate is computed, and the slave modem switches from blind timing recovery mode, to data directed timing recovery mode, after the Bit Error Rate has sufficiently decreased.Type: GrantFiled: March 18, 1999Date of Patent: July 26, 2005Assignee: Infineon Technologies AGInventors: Boaz Porat, Amnon Harpak, Shimon Peleg

Patent number: 6088368Abstract: The present invention provides a facility transport system for transporting Ethernet over digital subscnber lines. The system, termed 10BaseS, is capable of transmitting 10 Mbps Ethernet over existing copper infrastructure. The system utilizes carrierless amplitude modulation/phase modulation (CAP), a version of suppressed carrier quadrature amplitude modulation (QAM). The 10BaseS transport facility can deliver symmetrical data at approximately 13 Mbps (net 10 Mbps) over the unscreened, twisted pair telephone wires originally intended for bandwidths between 300 Hz and 3.4 KHz. The system utilizes frequency division multiplexing (FDM) to separate downstream channels from upstream channels. FDM is also used to separate both the downstream and upstream channels from POTS signals. The downstream and upstream data channels are separated in frequency from bands used for POTS and ISDN, enabling service providers to overlay 10BaseS on existing services.Type: GrantFiled: May 30, 1997Date of Patent: July 11, 2000Assignee: 3Com Ltd.Inventors: Avinoam Rubinstain, Yackov Sfadya, Shimon Peleg, Noam Alroy, Boaz Porat

Patent number: 5712867Abstract: A method, apparatus and system is described for distributing accurate time-of-day information from an existing telecommunications infrastructure without modifying the existing infrastructure. In particular, the system comprises a base station device which continually receives extremely accurate time-of-day information from, by way of example and not by limitation, a GPS (Global Positioning Satellite) system, a local atomic dock, or a wired or wireless time standard. The base station periodically places time-of-day information into standard paging packets for transmission over a standard paging network. The paging packets are sent over telephone lines to the paging terminal for transmission whenever a time slot for transmission becomes available. The base station device records the actual time of transmission of the paging packet containing the time of day information and prepares the next time-of-day packet by placing the exact transmission time of the previous time-of-day packet sent.Type: GrantFiled: March 3, 1995Date of Patent: January 27, 1998Assignee: NEXUS 1994 LimitedInventors: Hanoch Yokev, Yehouda Meiman, Shimon Peleg, Oren Yokev, Boaz Porat

Patent number: 5596330Abstract: A differential ranging location system is described which uses a modified time-of-arrival technique to determine the location of a frequency hopped spread spectrum radio signal. The transmitter simultaneously transmits two radio frequency carriers having different frequencies such that a phase difference is observed between the two carriers at a distance from the transmitter. The phase difference is proportional to the range from the transmitter that the carrier signals are observed. The two carrier signals from the single transmitter are received by at least three and in special cases four base stations which calculate the differential time of arrival based on the phase differences of the received carriers. The calculated phase differences are then sent to a central location which locates the position of the transmitter based upon a planer hyperbolic location algorithm.Type: GrantFiled: February 16, 1995Date of Patent: January 21, 1997Assignee: Nexus Telecommunication Systems Ltd.Inventors: Hanoch Yokev, Shimon Peleg, Yehouda Meiman, Boaz Porat
