摘要： A mobile device receives a signal, from a base station, comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device utilizes two different sampling rates to perform the PSS synchronization and the SSS detection individually. For example, the mobile device synchronizes to the received PSS at a first sampling rate such as 0.96 MHz, which is determined based on the PSS transmission rate and/or the length of the received PSS. The mobile device detects the received SSS at a second sampling rate such as 1.92 MHz, which equals to the sampling rate for an analog-to-digital conversion at the mobile device. The received PSS and associated symbol timing are detected through the PSS synchronization to support the SSS detection. The detected SSS is used to acquire cell-specific parameters such as cell ID. The acquired cell-specific parameters ensure proper communications between the mobile device and the base station.

摘要： A mobile device receives a radio frequency (RF) signal comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device performs multiple frequency hypothesis (MFH) testing via multiple MFH branches. A PSS correlation process is performed for each MFH branch. Frequency offset for receiving data is estimated using resulting correlation data. A desired offset is placed in each MFH branch. A baseband signal is frequency offset per MFH branch according to the desired frequency offset before the PSS correlation process. A received PSS is detected based on a maximum PSS correlation over the entire set of MFH branches. A frequency offset is estimated for the MFH branch associated with the detected PSS by combining an associated residual frequency with a corresponding desired offset. The frequency offset estimate is used for baseband signal processing and/or adjusting a reference oscillator frequency at the mobile device.

摘要： Methods and systems for dual frequency timing acquisition for compressed WCDMA communication networks may include processing received WCDMA signals. The WCDMA signals, which may be primary synchronization channel signals, may comprise signals transmitted by one base station at one frequency band and by another base station at a different frequency band, during a compressed frame. Samples of the received WCDMA signals from the different base stations may be stored in portions of a memory allocated for signals from each base station. The received WCDMA signals having the first frequency band may be processed via the processing circuitry during a non-compressed frame. The samples corresponding to the signals with the first frequency band during the non-compressed frame may be stored in the memory. The received WCDMA signals may be sampled at a faster rate during the non-compressed frame than during the compressed frame.

摘要： A multipath wireless communication is processed to recover a transmitted data signal without performing a direct matrix inversion (DMI). First, the multipath wireless communication is received. Then HHH and HHH values associated with the multipath wireless communication are determined. Weights based on HHH and HHH associated with the received data signal may then be determined and used to recover the transmitted data signal from the received multipath wireless communication.

摘要： A mobile device coupled to a common system clock receives a signal comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS) in a radio frame. Sample counts are generated for timed events based on corresponding operating bandwidths. The timed events are detected at modulo sample counts of the generated sample counts according to corresponding operating bandwidths. PSS symbol timing determined via the PSS synchronization is aligned to the generated sample counts based on corresponding operating bandwidth. The generated sample counts are bit-shifted relative to the aligned PSS symbol timing for other timed events based on corresponding operating bandwidths. The one or more timed events are determined via performing modulo counting after the bit-shifting. Timing operations are performed at the determined timed events and the determined one or more timed events are refined, accordingly.

摘要： A mobile device receives a signal, from a base station, comprising a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The received PSS and SSS are used to acquire cell-specific parameters so as to ensure communicates between the mobile device and the base station. The mobile device correlates the received signal in time domain using signs of each of a plurality of correlation reference sequences (reference PSSs). The mobile device generates sign based correlation reference PSSs using signs of the corresponding reference PSSs, which are generated based on a variety of Zadoff-Chu sequences. The received PSS is detected based on the correlation. No multiplication operations are used in the correlation process. Symbol timing is identified according to the detected PSS. The mobile device uses the identified symbol timing to baseband process the received signal. The received signal is an OFDM signal received over a 3GPP LTE/E-UTRA air interface.

摘要： A mobile device receives a radio frequency (RF) signal comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device performs multiple frequency hypothesis (MFH) testing via multiple MFH branches. A SSS decoding and a PSS correlation process are performed, respectively, per MFH branch. The SSS decoding may be performed according to corresponding PSS detection. Cell-specific information such as cell ID information and/or Cyclic Prefix (CP) length is acquired per MFH branch based on corresponding PSS detection and SSS decoding. Subsequently, the mobile device selects a particular MFH branch with a maximum PSS correlation peak over the entire MFH branches. The cell-specific information from the selected MFH branch is utilized for communications within a corresponding cell if the information is detected consistently. The mobile device compares cell ID information and/or CP length information over the remaining MFH branches for consistency check.

摘要： Aspects of a method and system for reducing the complexity of multi-frequency hypothesis testing using an iterative approach may include estimating a frequency offset of a received signal via a plurality of iterative frequency offset hypotheses tests. The iterative frequency offset hypotheses may be adjusted for each iteration. A correlation may be done between a primary synchronization signal (PSS), and one or more frequency offset versions of a received signal to control the adjustment of the iterative frequency offset hypotheses. A frequency of the received local oscillator signal may be adjusted based on the estimated frequency offset. One or more frequency offset version of the received signal may be generated via one or more multiplication, and the multiplication may be achieved via a multiplication signal corresponding to one or more frequency offsets. The frequency offset of the received signal may be estimated via the correlation.
