20140023168 | CROSS-CORRELATION RECEIVER - An embodiment of a receiver is proposed. The receiver includes a buffer element for receiving an input signal continuously, synchronization means for synchronizing the input signal by monitoring a buffer signal corresponding to the input signal within the buffer element at a corresponding monitoring time for determining a complete reception of at least one preamble signal within the buffer signal at a reception time, and by synchronizing the input signal according to the detection of the complete reception of the at least one preamble signal, and extraction means including at least one operative block configurable in an extraction phase for extracting a data signal associated with the at least one preamble signal from the input signal. In an embodiment, the synchronization means shares said at least one operative block with the extraction means; said at least one operative block is configurable in a synchronization phase for synchronizing the input signal. The operative block includes correlation means configurable in the synchronization phase for calculating at each monitoring time a correlation function between the buffer signal and a reference signal corresponding to the preamble signal, detection means configurable in the synchronization phase for detecting a partial reception of a significant portion of the preamble signal at a partial reception time according to the correlation function, and prediction means configurable in the synchronization phase for predicting the reception time according to the partial reception time. | 01-23-2014 |
