20090119570 | LOW COMPLEXITY BLIND TRANSPORT FORMAT DETECTION - The present invention relates to a method, apparatus and computer program product for detecting a transport format of a multiplexed transport channel used for transferring binary data, wherein a path metric value which estimates likelihood for a hypothetical trellis path to end at a predetermined state is determined for every state of a trellis stage of a possible end bit position of a data block of the transport channel. Then, for each possible end bit position a number of path metric values which indicate higher likelihood for the hypothetical trellis path to end at said predetermined state than an initial state is calculated, and the best end bit positions which lead to highest values of the calculated number are selected and error checking is performed for the selected best end bit positions to detect the transport format. The proposed selection of best end bit positions leads to a reduced number of decoding operations and thus to a reduced processing complexity. | 05-07-2009 |
20090180522 | FIRST SIGNIFICANT PATH DETECTION - A scheme determines the first significant path (FSP) of a received multipath signal, from data defining the relative delay and the amplitude of the individual signal paths occurring in a series of time frames. The scheme includes filtering the data to spread the signal paths, performing a persistence test between frames to reject spurious signal paths, combining the energy of the signal paths in a frame, applying a test to determine the time at which the combined energy satisfies a criterion, and selecting the FSP dependent on that time. The combined energy may be evaluated within a sliding window, and the position of the window within the frame determined that maximizes the combined energy. Alternatively, the combined energy may be evaluated as the cumulative energy through the frame, and the position determined at which the cumulative energy reaches a threshold. | 07-16-2009 |
20100105407 | WIRELESS TRANSMISSION POWER CONTROL METHOD AND SYSTEM - A wireless communication system includes a primary station which has a transmitter for transmitting wireless signals on a downlink, and a plurality of secondary stations each having a receiver for receiving signals on the downlink and a transmitter for transmitting on an uplink. In a normal, loaded condition a synchronization channel and a data channel are present on the downlink and closed power control is achieved by measuring the signal to interference ratio (SIR) in a received downlink transmission, comparing the measured SIR with a target SIR and sending a power adjust indication on the uplink to cause the primary station to adjust its transmitted power on the downlink. The secondary station monitors the downlink and, in response to detecting an unloaded cell condition, determines a target SIR offset which it applies to the target SIR to overcome interference from the presence of the synchronization channel on the downlink. | 04-29-2010 |

20130115902 | METHOD FOR TUNING AN OSCILLATOR FREQUENCY AND DEVICE IMPLEMENTING THE METHOD - A method for tuning an oscillator frequency produced in a radio-receiver chain is based on a slope analysis of a residual difference between the oscillator frequency and a carrier frequency of a radio-received signal. Depending on the slope value calculated, a bandwidth of a low-pass time-filtering that is effective for the frequency difference is increased or set back to a default value. The method provides an improved trade-off between tuning precision and dynamic behavior when the frequency difference drifts rapidly. | 05-09-2013 |
20140293818 | Non-Contiguous Carrier Aggregation - A method of operating a user equipment for measuring non-contiguous carriers comprises: changing a position of a local oscillator to be in the middle of the non-contiguous carriers; measuring the carriers simultaneously; estimating a power level of an interferer in a gap in the non-contiguous carriers which creates image interference; and compensating the measurement dependent on the interferer power level and an image rejection factor. | 10-02-2014 |
