摘要： A technique for determining a frequency offset between components of a communication network based on a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence is described. A method implementation of this technique comprises a provision of a set of correlation signals at different frequencies, with each correlation signal being indicative of a specific frequency offset hypothesis and comprising the CAZAC sequence. Once a synchronization signal comprising the CAZAC sequence is received, this synchronization signal is correlated with each of the correlation signals to obtain a correlation result for each frequency offset hypothesis. In a next step, at least one of the frequency offset hypotheses is selected based on a comparison of the correlation results. The frequency offset may then be determined based on the at least one selected frequency offset hypothesis.

摘要： The invention relates to a technique for controlling a synchronization of a terminal device (10) with a wireless network, e.g. an LTE network, wherein data are transmitted as a continuous data signal on a radio interface (11, 12) while being processed block-wise in the terminal (10). A method embodiment of the technique for achieving at least a downlink (11) synchronization comprises establishing a time-address mapping (TAM, 36) indicative of an association of a reference time value of an internal clock (32) with a reference address in the reception data buffer (16); determining an address of data samples representing the received data block in the reception data buffer (16) based on the time-address mapping; and initiating a block-wise reading of the data block from the reception data buffer (16) based on the determined address.

摘要： A technique for generating a Single-Carrier Frequency Division Multiple Access (SC-FDMA) signal based on a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence is disclosed. A method embodiment of this technique comprises generating a frequency domain representation of the CAZAC sequence by providing an analytical representation of the CAZAC sequence in the frequency domain with an integer phase term and calculating the integer phase term in a recursive manner for each of a plurality of frequency domain samples of the CAZAC sequence. The resulting frequency domain representation of the CAZAC sequence is then mapped to a pre-determined frequency location before being transformed into the time domain to obtain a time domain representation of the SC-FDMA signal. The SC-FDMA signal may be a random access signal for transmission on a Physical Random Access Channel (PRACH).

摘要： A technique for cell signature determination in a cellular communication network is provided. A method implementation of this technique comprises the steps of providing a set of hypothesis signals, each hypothesis signal including a signature hypothesis, receiving a composite signal including a first signal portion carrying a first signature from a first cell and a second signal portion carrying a second signature from a second cell, wherein the first signal portion and the second signal portion overlap at least partially in time, and obtaining a correlation result by correlating the composite signal with each hypothesis signal. After the first signature has been determined, a set of phantom signatures associated with the first signature is provided. The phantom signatures represent artifacts from the first signal portion in the correlation result. Finally, the second signature is determined based on the correlation result taking into account the set of phantom signatures associated with the first signature.
