    Abstract: Techniques for detecting discontinuous transmission (DTX) are disclosed. In an example method, given a sequence of bits that is known by a wireless receiver to be included in transmission bursts targeted to the wireless receiver and given a series of received signal samples corresponding to an expected transmission burst for the wireless receiver, the wireless receiver estimates a channel response and a location for the sequence within the series. The wireless receiver generates a plurality of bit estimates from the subset of received signal samples, based on the estimated channel response, compares the bit estimates to bits in the sequence of bits, and determines whether a valid burst for the wireless receiver is present, based on said comparing. The disclosed techniques are particularly suitable for use in detecting DTX in VAMOS scenarios.

    Abstract: A method and apparatus for decoding portions of a data stream, wherein each portion comprises a plurality of samples. The method comprises storing portions of the data stream, decoding portions of the data stream to form decoded portions, and storing the decoded portions. The method further comprises identifying that a portion of the data stream is degraded. Following identifying that a portion of the data stream is degraded, the method generates a decoded portion for the degraded portion of the data stream using the stored decoded portions. The method also updates a state of a decoder by: estimating a pitch period of the degraded portion; selecting a group of successive samples of the stored portions of the data stream, the group of successive samples offset from the degraded portion in the data stream by a multiple of the estimated pitch period; and decoding the selected samples at the decoder.

    Abstract: In a signal detection apparatus, power detection section 101 detects power of an inputted received signal, and upon detection of power exceeding a power detection threshold, outputs a trigger to storage section 102. Storage section 102 stores a first received signal upon reception of the trigger and outputs the stored first received signal to multiplier 103 and newly stores a second received signal upon receipt of the next trigger. Multiplier 103 multiplies the second received signal by the first received signal, integrator 104 integrates the multiplication result from multiplier 103 during a predetermined duration to obtain a correlation value of the second and first received signals, and absolute value calculation section 105 calculates an absolute value of the correlation value from integrator 104. Determination section 106 determines the presence/absence of a detection-target signal based on the absolute value of the correlation value from absolute value calculation section 105.

    Abstract: In the field of mobile telecommunications, a method for checking a false alarm is provided. In the method, after a user in a Long Term Evolution (LTE) system receives control signaling for scheduling physical resources, Cyclic Redundancy Check (CRC) is performed on the control signaling; and if the CRC is passed, false alarm check is performed on the control signaling according to false alarm check bit(s) and padding bit(s) in the control signaling. An apparatus and a user equipment (UE) for checking a false alarm are also provided. According to the method, the apparatus, and the UE for checking a false alarm, the number of bits participating in the false alarm check is increased, thereby reducing the probability of false alarm occurrence, and improving receiving performance of the control signaling.

    Abstract: A method of data classification for use in a wireless communication system includes obtaining decoder metrics from a decoder. The decoder metrics correspond to data generated by the decoder. The decoder metrics include a symbol error rate (SER) and an energy metric (EM). The method also includes classifying the data into a first category if the data fails a cyclic redundancy check (CRC) check, into a second category if the data passes the CRC check and is determined to be unreliable, or into a third category if the data passes the CRC check and is determined to be reliable. A reliability of the data is determined based on the decoder metrics and an EM threshold.
