Abstract: This invention concerns a resynchronization method by a receiver of a received stream of groups of bits, comprising: detecting a synchronization loss (S10), and then iterating (S11 to S17) checks over different bits until a first bit of a group of bits is found (S14), the most probable first bit being checked first, wherein the checks are iterated in a checking order of bits different from a chronological reception order, so as to check earlier at least one of most probable first bits, different from the most probable first bit, so as to shorten average resynchronization time.

Abstract: A Reference Signal Received Power (RSRP) value is produced from a received Orthogonal Frequency Division Multiplexed (OFDM) signal that comprises a plurality of reference symbols located at known sub-carrier frequencies and times within the received OFDM signal. RSRP value production involves, for each hypothesized error state selected from a plurality of different hypothesized error states, ascertaining a corresponding hypothesized RSRP value, and then using the hypothesized RSRP values as a basis for determining a value for use as the produced RSRP value (e.g., by selecting a maximum one of the hypothesized RSRP values as the produced RSRP value). In this technology, each of the hypothesized error states is a hypothesized frequency error paired with a hypothesized timing error and the corresponding hypothesized RSRP value is produced by adjusting one or more measured channel estimates as a function of the hypothesized error state.

Abstract: The present subject matter discloses a system and a method for processing of channel coefficients of networks. In one embodiment, the method includes ascertaining at least one probable synchronization position of a received sequence and projecting, by oblique projection, at least one given noise basis vector spanning a given noise space onto the null space, so as to determine a channel impulse response at the at least one probable synchronization position. Based on a criterion related to the channel impulse response, a synchronization point for the received sequence is identified from the at least one probable synchronization position. The method also includes determining the noise contribution at the synchronization point and determining the noise coefficient of the at least one given noise basis vector based on the noise contribution so as to recover a signal substantially similar to the originally transmitted signal.

Abstract: The present subject matter discloses a system and a method for estimating a frequency offset in communication devices. In one embodiment, the method of estimating a frequency offset in a communication device comprises generating a reconstructed signal based at least in part on a channel impulse response (CIR) corresponding to a received signal. Further, a normalization matrix is determined for the reconstructed signal. Thereafter, based at least in part on the normalization matrix and the reconstructed signal, the frequency offset is estimated such that the frequency offset corresponds to a maximum normalized-correlation between the reconstructed signal and the received signal.
