  • Patent number: 8649752
    Abstract: 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.

  • Publication number: 20140023162
    Abstract: Aspects of a method and system for an OFDM joint timing and frequency tracking system may include tracking carrier frequency and symbol timing in an Orthogonal Frequency Division Multiplexing (OFDM) signal based on at least a reference symbol set. A receiver frequency and timing may be adjusted based on the tracked carrier frequency and symbol timing. The carrier frequency may be tracked by generating an output signal as a function of a frequency offset ?f, and the symbol timing may be tracked by generating an output signal as a function of a guard time ?tg The received OFDM signal may be fast Fourier transformed to generate the reference symbol (RS) set. The receiver frequency and timing may be adjusted coarsely prior to fine adjustment. The coarse receiver frequency and the timing adjustment may be based on processing a primary synchronization signal and a secondary synchronization signal.

  • Patent number: 8634487
    Abstract: A mobile device in an OFDM system receives an OFDM signal comprising RS tones and data OFDM symbols. The received RS tones are extracted for channel estimation using a masking operation. Masking parameters are determined by matching channel time variance using corresponding time domain samples of the extracted RS tones. As approximated channel impulse responses of transmission channels, the time samples are masked to perform the channel estimation. The channel time variance comprising inter-carrier interference and delay spread are measured, respectively. A mean of differences in power between neighbor adjacent subcarriers of the extracted RS tones is used for the inter-carrier interference measurement. The delay spread measurement such as root-mean-squared (RMS) delay spread is calculated using the approximated channel impulse responses.

  • Patent number: 8614994
    Abstract: 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.

The cyclic prefix length may be selected from a finite set of possible cyclic prefix lengths. The cyclic prefix length may be, for example, 9 samples or 32 samples. The primary synchronization sequence synchronization may be determined via correlation.

  • Patent number: 8576830
    Abstract: A mobile device receives a signal comprising a PSS and performs multiple frequency hypothesis testing (MFHT) on the received signal. The mobile device starts MFHT by applying different initial frequency offsets in corresponding MFH branches. Timing drift in MFHT is compensated based on corresponding initial frequency offsets. In this regard, a PSS correlation process is performed on the received signal in each MFH branch. Resulting PSS correlation data is buffered and processed in corresponding PSS timing hypothesis buffers. The timing position of samples is updated in the PSS timing hypothesis buffers based on corresponding initial frequency offsets. Energy associated with the PSS transmissions may be accumulated utilizing corresponding PSS correlation data at updated sampling positions. The received PSS is detected based on a maximum accumulated energy associated with the PSS transmissions. Information that comes from the detected PSS is utilized by the mobile device to camp on a corresponding cell.
