Patent number: 10187240Abstract: A system and method that scrambles the phase characteristic of a carrier signal are described. The scrambling of the phase characteristic of each carrier signal includes associating a value with each carrier signal and computing a phase shift for each carrier signal based on the value associated with that carrier signal. The value is determined independently of any input bit value carried by that carrier signal. The phase shift computed for each carrier signal is combined with the phase characteristic of that carrier signal so as to substantially scramble the phase characteristic of the carrier signals. Bits of an input signal are modulated onto the carrier signals having the substantially scrambled phase characteristic to produce a transmission signal with a reduced PAR.Type: GrantFiled: September 1, 2017Date of Patent: January 22, 2019Assignee: TQ DELTA, LLCInventor: Marcos C. Tzannes

Patent number: 10049003Abstract: The ability to accurately and efficiently calculate and report communication errors is becoming more important than ever in today's communications environment. More specifically calculating and reporting CRC anomalies in a consistent manner across a plurality of communications connections in a network is crucial to accurate error reporting. Through a normalization technique applied to a CRC computation period (e.g., the PERp value), accurate error identification and reporting for each individual connection can be achieved.Type: GrantFiled: March 7, 2016Date of Patent: August 14, 2018Assignee: TQ DELTA, LLCInventor: Marcos C.

Patent number: 10044473Abstract: A system that includes a multicarrier transceiver including a processor and memory. The system transmitting a packet using a forward error correction encoder and an interleaver, wherein the packet comprises a header field and a plurality of bytes, and wherein the header field comprises a sequence identifier (SID) and receiving at least one message using a forward error correction decoder and without using a deinterleaver, wherein the at least one message is received in a single DMT symbol and wherein the at least one message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the transmitted packet. An SNR margin of the at least one message is greater than an SNR margin of the packet.Type: GrantFiled: October 20, 2016Date of Patent: August 7, 2018Assignee: TQ DELTA, LLCInventor: Marcos C.

Patent number: 9973624Abstract: Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.Type: GrantFiled: February 5, 2016Date of Patent: May 15, 2018Assignee: TQ DELTA, LLCInventors: David M. Krinsky, Robert Edmund Pizzano, Jr.

Patent number: 9898220Abstract: A transceiver is designed to share memory and processing power amongst a plurality of transmitter and/or receiver latency paths, in a communications transceiver that carries or supports multiple applications. For example, the transmitter and/or receiver latency paths of the transceiver can share an interleaver/deinterleaver memory. This allocation can be done based on the data rate, latency, BER, impulse noise protection requirements of the application, data or information being transported over each latency path, or in general any parameter associated with the communications system.Type: GrantFiled: December 8, 2016Date of Patent: February 20, 2018Assignee: TQ DELTA, LLCInventors: Marcos C. Tzannes, Michael Lund

Patent number: 9894014Abstract: A device that includes a plurality of transceivers configurable to simultaneously operate with a combination of bonded and unbonded transceivers. A first transceiver of the plurality of transceivers is operable at a first data rate, and a second transceiver of the plurality of transceivers is simultaneously operable at a second data rate that is different than the first data rate. The first and second transceivers are operable as bonded transceivers and wherein a third transceiver, of the plurality of transceivers, is simultaneously operable at a third data rate and the third transceiver is not bonded with any other transceiver.Type: GrantFiled: March 1, 2016Date of Patent: February 13, 2018Assignee: TQ DELTA, LLCInventors: Marcos C.

Patent number: 9749235Abstract: Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.Type: GrantFiled: June 17, 2015Date of Patent: August 29, 2017Assignee: TQ DELTA, LLCInventor: Marcos C.

Patent number: 9621198Abstract: With the current initialization procedures defined in the VDSL and ADSL standards, even though the xDSL system could operate in Showtime in an impulse noise environment where symbols are being corrupted, the transceivers would not be able to reach Showtime because initialization would fail due to initialization message failure. Through the use of an improved initialization procedure for communication systems, operation in environments with higher levels of impulse noise is possible.Type: GrantFiled: December 3, 2014Date of Patent: April 11, 2017Assignee: TQ DELTA, LLCInventor: Marcos C.
