Patent number: 8805274Abstract: An architecture and protocol enables signal communications between either a frequency translation module and a decoder within a dwelling, or between an antenna and a decoder within a dwelling. According to an exemplary embodiment, the decoder comprises a switch 33 between the low noise block converter power supply, and a transceiver and output coupling. The switch 33 generates a high impedance during operation of the frequency translation module and the LNB power supply 38, thereby isolating the transceiver and the output coupling from the LNB power supply. The switch generates a low impedance between the LNB power supply and the transceiver and output coupling during operation of the LNB power supply.Type: GrantFiled: January 25, 2007Date of Patent: August 12, 2014Assignee: Thomson LicensingInventors: John James Fitzpatrick, Lincheng Xiu

Patent number: 8688054Abstract: A method and apparatus for adaptively biasing a channel quality indicator (CQI) used for setting a configuration of communication between a transmitter and a receiver in a wireless communication system. The receiver sends a CQI and positive acknowledgement (ACK)/negative acknowledgement (NACK) messages to the transmitter. The ACK/NACK messages indicate the absence or presence of error, respectively, in a transmitted data packet. The CQI is derived from the signal-to-interference ratio (SIR) and the ACK/NACK messages. The transmitter calculates the block error rate (BLER) of the transmitted data packets based upon the ACK/NACK messages sent from the receiver. The transmitter compares the BLER of the transmitted data packets to a target BLER and biases the CQI based on the comparison in order to achieve the target BLER.Type: GrantFiled: November 21, 2008Date of Patent: April 1, 2014Assignee: InterDigital Technology CorporationInventors: Philip J. Pietraski, Gregory S. Sternberg, Douglas R. Castor

Patent number: 8670707Abstract: A communication system is provided that allows the use of low-cost, low-power remote terminal units that communicate substantially asynchronously and independently to a base station. To minimize cost and complexity, the remote terminal units are configured similarly, including the use of substantially identical transmission schemes, such as a common Direct Sequence Spread Spectrum (DSSS) code. To minimize collisions among transmissions, the communication system is designed to use a high-gain antenna with a limited field of view, to limit the number of cotemporaneous, or overlapping transmissions that are received at the base station. To cover a wide area, the limited field of view is swept across the area of coverage. To overcome potential losses caused by collisions, the remote terminal units are configured to repeat transmissions; to minimize repeated collisions, the repeat interval and/or duration is randomized.Type: GrantFiled: March 16, 2012Date of Patent: March 11, 2014Assignee: Orbcomm Sens, LLCInventors: Richard D. Fleeter, John E. Hanson, Scott A. McDermott, Raymond G. Zenick, Jr.

Patent number: 8660479Abstract: A digital radio broadcast system includes a processing system that receives first audio content, first program data identifying a first item for the first audio content, second audio content, and second program data identifying a second item for the second audio content such that a start of the first program data is received at the processing system within 0.5 seconds of a start of the first audio content. A digital radio broadcast signal including the audio content and the program data is processed for digital radio broadcast transmission via a transmitter. The processing system stops delivery of the first program data to the transmitter upon receipt of the second program data, the first program data thereby being truncated, and begins delivery of the second program data to the transmitter. A digital radio broadcast receiver can tag content of interest based on a user command registered at the receiver.Type: GrantFiled: August 2, 2010Date of Patent: February 25, 2014Assignee: iBiquity Digital CorporationInventors: Steven Andrew Johnson, Robert Michael Dillon, Harvey Chalmers

Patent number: 8655396Abstract: A method for a wireless communication includes receiving or storing a peak to average (PAR) back off value; and applying the PAR back off value to determine the transmission power and rate for SIMO and MIMO transmissions. In one aspect, the PAR back off value is at least partially based on modulation type. In another aspect, the PAR back off value is more for higher order QAM than for QPSK. The power allocation algorithm for different UL MIMO schemes is described as follows. For MIMO without antenna permutation (e.g. per antenna rate control), different PAR back off values are considered for different data streams. For MIMO with antenna permutation or other unitary transformation such as virtual antenna mapping or precoding, the PAR back off are determined based on combined channel. The transmission data rate depends on power and also the receiver algorithms such as a MMSE receiver or MMSE-SIC receiver.Type: GrantFiled: November 6, 2007Date of Patent: February 18, 2014Assignee: QUALCOMM IncorporatedInventors: Durga Prasad Malladi, Hao Xu
