Abstract: Long time interleaver and listenable audio performance enhancements for a satellite receiver are presented. One enhancement includes comparing a correlation and a predetermined threshold value and blocking satellite signal data transmission from entry into long time interleaver (LTI) device circuitry and forward error correction (FEC) circuitry when the correlation value is the same as, or less than the predetermined threshold value. Another enhancement includes using Reed-Solomon codeword error checking to prevent erroneous baseband signal data from being accepted as good baseband signal data. A further enhancement includes storing symbol timing and frequency data during a strong signal condition of the satellite receiver and using this stored data when the satellite receiver encounters a weak signal condition. Another enhancement includes mitigating DC offset noise in a satellite receiver having a zero-IF tuner.

Abstract: A user equipment (UE) operating in a wireless network receives a sequence of speech frames on a speech channel. The UE demodulates at least a portion of a speech frame of the sequence of received speech frames to produce a metric value. The UE discontinues processing of the speech frame and enters a low power discontinuous reception (DRX) mode if the metric value indicates absence of valid speech data, and ignores and does not demodulate at least the next remaining bursts of the speech frame after entering DRX mode.

Abstract: The present invention relates to ACK-NACK detection in an LTE wireless communication system. To determine a threshold value for an ACK-NACK transmission, an SC-FDMA signal is received from user equipment. Then, a power estimate of soft data bits is used to establish a threshold value for determining the presence of an ACK-NACK signal. Using this threshold value, a signal from the user equipment is analyzed to determine if it contains an ACK or NACK transmission.

Abstract: Apparatus and methods for selective decoding of received code blocks are disclosed. An example method includes receiving a code block, determining a code block quality indicator for the received code block, and attempting to decode the received code block if the code block quality indicator is greater than or equal to a threshold. If the code block quality indicator is less than the threshold, the received code block is discarded without decoding attempts. The threshold may be a static or dynamic threshold.

Abstract: Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

Abstract: A transceiver apparatus, a receiver and a power saving method thereof are provided. The receiver includes an analog-to-digital converter, an equalizer, a slicer, a delay unit, a decoder, a select unit and a control unit. The analog-to-digital converter transforms a received signal into a digital signal. The equalizer adjusts the digital signal to generate an equalized signal. The slicer receives and slices the equalized signal and generates a sliced signal. The delay unit delays the sliced signal. The decoder determines whether to decode the equalized signal or not according the control signal. The select unit selects one of the output of the delayed sliced signal and the output of the decoder to be an output signal according to a second control signal. The control unit determines whether to enable the control signal and the second control signal according to the state of the sliced signal and the output signal.

Abstract: A method, system, network and device provide Smart Grid RFI detection. One or more symbols or chips present in one or more received radio frequency signals are detected and the presence of one or more erred symbols or chips in the detected one or more symbols present in the received one or more radio frequency signals determined. A correlation in time between the one or more erred symbols or chips and an infrastructure waveform associated with electrical infrastructure can be determined. When the determined correlation indicates the electrical infrastructure as a source of detectable radio frequency interference to a device, a pattern flag is generated. The pattern flag or pattern flag representation can be stored and/or transmitted.
