Abstract: A receiver component and a method for enhancing a detection range of a time synchronization process in a receiver utilize multiple cross-correlations of a received signal with a known preamble sequence. The results of the multiple cross-correlations are divided into delay segments. The delay segments of one of the multiple cross-correlations are compared with the delay segments of another of the multiple cross-correlations to determine delay of the delay segments of the one of the multiple cross-correlation results.

Abstract: A method for iterative decoding a data transfer structure comprising a plurality of code blocks includes: decoding a code block of the data transfer structure in a first iteration; determining a quantity indicative of a performance of the decoding of the code block; if the quantity indicates a decoding failure, decoding the code block again in subsequent iterations until a stopping criterion is reached, wherein the stopping criterion is based on a predetermined number of iterations per code block and a predetermined number of iterations per data transfer structure.

Abstract: Sphere decoding of signals for MIMO detection involves a first distance processor arranged to determine a distance between symbols of a received symbol vector and possible transmit symbols, in a search sequence according to a search tree. A line from root to leaf of the search tree represents a possible transmit symbol vector and the sequence of processing root level symbols can be ordered with respect to increasing distance without explicit sorting of the root level symbols based on distance calculations. A next symbol in the sequence is determined, based on a symbol currently being processed by the first distance processor, and a second distance processor determines the distance in respect of the next symbol in the search sequence for the same possible transmit symbol vector, in parallel with the determining of the distance in respect of the current symbol by the first distance processor.

Abstract: A low complexity method for determining a search sequence of nodes for an efficient soft-decision sphere decoding algorithm for use in receivers for quadrature amplitude modulation (QAM) communication signals is achieved by determining a first member of the search sequence by rounding a received symbol (z) to a first constellation symbol (xc) of the QAM constellation, classifying the remaining constellation symbols (xi) of the QAM constellation into a plurality of sub-sets of constellation symbols having the same distance metric relative to said first constellation point (xc) according to a metric dsequ(n)=2a·n=max{|real(xc?xi)|,|imag(xc?xi)|}, a being a scaling factor of the constellation grid, and ordering said sub-sets of constellation symbols in ascending order of their distance metric relative to the first constellation symbol (xc), and ordering the members of each sub-set of constellation symbols that are defined by the same distance metric according to their Euclidean distances.

Abstract: A method is provided for decoding data packets in wireless communication schemes that use a Hybrid Automatic Repeat Request technique, and a receiver for wireless communication that performs such a method. The HARQ memory incorporated in a receiver for wireless communication is minimized to a size which only reserves memory for an average number of erroneous sub-packets. Following decoding, an error check is performed on a per sub-packet basis, and only the softbits of those sub-packets for which decoding errors have been detected are stored in the HARQ memory. Correctly decoded sub-packets are stored in a separate memory. This significantly decreases the size of the HARQ memory required at the receiver which is beneficial in terms of both silicon area and power consumption.
