    摘要: A method of generating an interleaved symbol sequence location from a symbol location of a symbol sequence comprises determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location. This is done by acquiring values of the interleaver sequence function in quotient and remainder form and then calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form.

    摘要: Described embodiments provide a wideband code division multiple access (W-CDMA) system, that employs an interleaving rule having a modified pruning algorithm. Interleaving, by pruning a sequence of bits in the W-CDMA system, includes determining a non-pruned interleaved vector having a length N. The determination of the non-pruned interleaved vector is based on a received length of an input vector from the sequence of bits. The input vector is padded. An interleaver generates a pre-pruned interleaved vector having a length equal to the length N, wherein the pre-pruned interleaved vector is a function of the padded input vector and the non-pruned interleaving vector. The interleaver prunes one or more elements from the pre-pruned interleaved vector based on a corresponding pruning indication in a pruning indication table, thereby providing a pruned interleaved vector as a portion of the interleaved sequence of bits.

    摘要: A 2-dimensional interleaving method is disclosed. The method comprises dividing a frame of input information bits into a plurality of groups and sequentially storing the divided groups in a memory; permuting the information bits of the groups according to a given rule and shifting an information bit existing at the last position of the last group to a position preceding the last position; and selecting the groups according to a predetermined order, and selecting one of the information bits in the selected group.

    摘要: An interleaver address generator is provided with pruning avoidance technology. It anticipates the points in time when incorrect addresses are computed by an IAG, and bypasses these events. It produces a stream of valid, contiguous addresses for all specified code block sizes. A single address computation engine firstly ‘trains’ itself about violating generated addresses (for a related block size) during the initial H1 half-iteration of decoder operation, and then produces a continuous, correct stream of addresses as required by the turbo decoder. Thus regions of pruned addresses are determined, and then training is performed only in these regions. Thus, computation and population of a pruned event table is determined in less than 1/10 the time required to do a conventional style full training. The resulting pruned event table is compressed down to 256 bits.

    摘要: A system and method for interleaving data in a wireless transmitter wherein bits from the input data stream are sent to downstream processing without being stored in memory. According to a first example embodiment of the present invention, a first radio frame of data from an input code block is sent downstream, and the remaining radio frames from the code block are stored in the memory buffer. The first interleaving pattern can be applied, for example, as data is written to or read from the memory buffer. The stored radio frames are then read out as needed by the downstream processing. According to a second example embodiment of the present invention, further savings in memory can be achieved by discarding bits that are not currently needed for processing then recalculating them at a later time. A first radio frame of data from an input code block is sent downstream without being stored in the memory buffer. Additional radio frames from the input code block may be stored in the memory buffer, and the remaining frames are discarded. Those radio frames stored in the memory buffer are then read out as needed by downstream processing. The input code block is then recalculated by the operations upstream from the first interleaver, and the sending downstream, storing, and discarding operations are repeated until the remaining radio frames have been provided to downstream processing.

    摘要: A method for data interleaving and data de-interleaving against periodical position interference, the process of data interleaving includes: multiplexing data of different transport channels, interleaving the data multiplexed, and Outputting the data interleaved; the process of data de-interleaving includes: receiving the data interleaved, de-interleaving the data received, and de-multiplexing the data de-interleaved into different transport channels; performing a randomized operation in the process of the data interleaving and an inverse operation of the randomized calculation in the process of the data de-interleaving to make the outputted position of the data of different transport channels after the interleaving be random. It may be avoided by applying the present invention that all synchronization interference signals in a wireless channel are concentrated in the data of the same transport channel.
