| 20090034484 | Synchronization channel noise power estimation - Apparatus and method to process a pilot channel and a synchronization channel to obtain a combined noise estimate of the pilot channel and the synchronization channel that is synchronized to the pilot channel. The combined noise estimation is processed to determine a first noise component for a period when both the pilot channel and the synchronization channel are present. Then, the combined noise estimate is processed to determine a second noise component for a period when only the pilot channel is present. Next, the second noise component is subtracted from the first noise component to derive a noise estimation for the synchronization channel. The technique may be applied to the Common Pilot Channel (CPICH), and the Synchronization Channel (SCH) defined in a 3 | 02-05-2009 |
| 20090036059 | Apparatus and method for E-HICH/E-RGCH processing, metric estimation and detection - Apparatus and method for processing a received pilot to obtain noise estimation of a pilot channel and processing a received first signal channel, separately from a second signal channel that is orthogonal to the first signal channel, to obtain a signal level of the first signal channel. The noise estimation and the signal level are used to calculate a SNR value. Detection on the first channel is done by checking the SNR and the sign of a soft metric. | 02-05-2009 |
| 20090036155 | E-HICH/E-RGCH adaptive threshold setting - Performing adaptive threshold setting by placing a receiver in a mode where a first signal indication and a second signal indication are certain not to occur from a transmitter. Once in that mode, the receiver adjusts a first threshold level for receiving the first signal by noting a false indication of receiving the first signal and adjusts a second threshold level for receiving the second signal by noting a false indication of receiving the second signal. | 02-05-2009 |
| 20110064122 | METHOD AND SYSTEM FOR PROCESSING SIGNALS UTILIZING A PROGRAMMABLE INTERFERENCE SUPPRESSION MODULE - Aspects of a method and system for processing signals utilizing a programmable interference suppression module are provided. In this regard, a received signal may be iteratively processed to generate an interference suppressed representation of the received signal. The iterative processing may comprise a weighting iteration; an addback weighting and un-addback iteration, and an addback iteration. The weighting iteration may comprise generating one or more first estimate signals that estimate user signals present in the received signal. The addback, weighting, and un-addback iteration may comprise generating one or more incremental estimate signals based on the one or more first estimate signals and the one or more second estimate signals. The addback iteration may comprise generating an interference suppressed representation of the received signal based on at least the one or more second estimate signals. | 03-17-2011 |
| 20110075648 | METHOD AND SYSTEM FOR WCDMA/HSDOA TIMING ADJUSTMENT - Aspects of a method and system for WCDMA/HSDPA timing adjustment may include adjusting an uplink transmission timing of a signal for transmission by a large adjustment step, utilizing a plurality of smaller adjustment steps, to generate an adjusted transmission signal. The transmission signal may be upsampled to a rate corresponding to the smaller adjustment step, which may generate an upsampled transmission signal. An adjusted upsampled transmission signal may be generated by inserting one or more of the smaller adjustment steps via one or more extra samples into the upsampled transmission signal to generate a delay, or removing one or more samples from the upsampled transmission signal to generate an advance. The adjusted upsampled transmission signal may be filtered and downsampled to generate the adjusted transmission signal. | 03-31-2011 |
| 20110075708 | METHOD AND SYSTEM FOR PER-CELL INTERFERENCE ESTIMATION FOR INTERFERENCE SUPPRESSION - A wireless system may receive a plurality of multipath signals from a plurality of transmitters and allocate per-cell modules for generating an interference suppressed signal from the multipath signals. Data symbols may be sequentially processed in the received multipath signals utilizing the per-cell modules and subtracting the processed symbols from a residual buffer storing the received multipath signals. Desired information received from one or more of the transmitters may be recovered utilizing the interference suppressed signal. Timing of the data symbols may be correlated utilizing a cell chip combiner. The data symbols may be descrambled utilizing conjugated scrambling codes associated with one of the plurality of transmitters. Orthogonal variable spreading factor (OVSF) codes may be generated utilizing a Walsh transform on the data symbols. Power levels of the OVSF codes may be estimated and estimated signals may be generated based on the OVSF codes and the estimated power levels. | 03-31-2011 |
| 20110151888 | METHOD AND SYSTEM FOR A PROGRAMMABLE INTERFERENCE SUPPRESSION MODULE - Aspects of a method and system for a programmable interference suppression module may include receiving a communication signal comprising one or more desired signal, and one or more undesired signals. The communication signal may be utilized to generate estimated channel state information. The estimated channel state information may be formatted for use in interference suppression. A reduced interference signal may be generated from a delayed version of said communications signal and the estimated channel state information, wherein the one or more undesired signals may be attenuated. The reduced interference signal may be formatted for post-processing. The desired signals may comprise WCDMA and/or HSDPA signals, and the undesired signals may be inter-cell and/or intra-cell interference. Further processing may comprise HSDPA processing and/or RAKE finger processing. The communication signal may be a Universal Mobile Telecommunication System (UMTS) compliant signal. | 06-23-2011 |
