Abstract: Turbo decoder employing ARP (almost regular permutation) interleave and inverse thereof as de-interleave. A novel means is presented herein by which a common module can perform both ARP interleaving and ARP de-interleaving during turbo decoding processing. A novel approach is presented that allows a common structure to perform both the interleaving and de-interleaving operations. In some embodiments, certain ARP interleaving parameters are processed to generate ARP de-interleaving parameters. In even other embodiments, certain ARP interleaving parameters are processed to generate an algebraic, closed form ARP de-interleaver function that can be employed during turbo decoding processing. This novel approach obviates the need for extremely large pre-computed look-up-tables. Moreover, this novel approach can accommodate many different interleaves and information block sizes with very little overhead.

Abstract: Address generation for contention-free memory mappings of turbo codes with ARP (almost regular permutation) interleaves. A novel means is presented by which anticipatory address generation is employed using an index function , that is based on an address mapping , which corresponds to an interleave inverse order of decoding processing (??1). In accordance with parallel turbo decoding processing, instead of performing the natural order phase decoding processing by accessing data elements from memory bank locations sequentially, the accessing of addresses is performed based on the index function , that is based on an mapping and the interleave (?) employed within the turbo coding. In other words, the accessing data elements from memory bank locations is not sequential for natural order phase decoding processing. The index function of also allows for the interleave (?) order phase decoding processing to be performed by accessing data elements from memory bank locations sequentially.

Abstract: A technique to determine carrier frequency offset (CFO) phase shift and perform channel estimation for symbols of a signal communicated across a multiple-input-multiple-output (MIMO) communication channel, in which preambles utilized for channel estimation are sent over more than one time block. Because the transmission of preambles used for channel estimation are sent over multiple time blocks, a CFO phase shift that is flat across tones of an OFDM signal is experienced between preambles of the two time blocks. Upon detection of the CFO phase shift, a weighting matrix used for channel estimation is modified to account for the CFO phase shift, in order to perform the channel estimation with correction for the CFO phase shift.

Abstract: A technique to determine sampling frequency offset (SFO) phase shift and perform channel estimation for symbols of a signal communicated across a multiple-input-multiple-output (MIMO) communication channel, in which preambles utilized for channel estimation are sent over more than one time block. Because the transmission of preambles used for channel estimation are sent over multiple time blocks, a SFO phase shift that is linear across tones of an OFDM signal is experienced between preambles of the two time blocks. Upon detection of the SFO phase shift, a weighting matrix used for channel estimation is modified to account for the SFO phase shift, in order to perform the channel estimation with correction for the SFO phase shift.

Abstract: Turbo decoder employing ARP (almost regular permutation) interleave and arbitrary number of decoding processors. A novel approach is presented herein by which an arbitrarily selected number (M) of decoding processors (e.g., a plurality of parallel implemented turbo decoders) be employed to perform decoding of a turbo coded signal while still using a selected embodiment of an ARP (almost regular permutation) interleave. The desired number of decoding processors is selected, and very slight modification of an information block (thereby generating a virtual information block) is made to accommodate that virtual information block across all of the decoding processors during all decoding cycles except some dummy decoding cycles. In addition, contention-free memory mapping is provided between the decoding processors (e.g., a plurality of turbo decoders) and memory banks (e.g., a plurality of memories).

Abstract: Tail-biting turbo code for arbitrary number of information bits. A novel means is presented in which, for most cases, no extra symbols at all need to be padded to an input sequence to ensure that a turbo encoder operates according to tail-biting (i.e., where the beginning and ending state of the turbo encoder is the same). In a worst case scenario, only a single symbol (or a single bit) needs to be padded to the input sequence. Herein, all of the input bits of the input sequence are interleaved within the turbo encoding. In the instance where the at most one symbol (or at most one bit) needs to be padded to the input sequence, then that at most one symbol (or one bit) is also interleaved within the turbo encoding. Moreover, any size of an input sequence can be accommodated using the means herein to achieve tail-biting.

Abstract: General and algebraic-constructed contention-free memory mapping for parallel turbo decoding with algebraic interleave ARP (almost regular permutation) of all possible sizes. A novel means is presented in which contention-free memory mapping is truly achieved in the context of performing parallel decoding of a turbo coded signal. A novel means of performing the contention-free memory mapping is provided to ensure that any one turbo decoder (of a group of parallel arranged turbo decoders) accesses only memory (of a group of parallel arranged memories) at any given time. In doing so, access conflicts between the turbo decoders and the memories are avoided.

Abstract: Reduced complexity ARP (almost regular permutation) interleaves providing flexible granularity and parallelism adaptable to any possible turbo code block size. A novel means is presented by which any desired turbo code block size can be employed when only requiring, in only some instances, a very small number of dummy bits. This approach also is directly adaptable to parallel turbo decoding, in which any desired degree of parallelism can be employed. Alternatively, as few as one turbo decoder can be employed in a fully non-parallel implementation as well. Also, this approach allows for storage of a reduced number of parameters to accommodate a wide variety of interleaves.
