  • Encoding module, apparatus and method for determining a position of a data bit within an interleaved data stream
    Patent number: 8638244
    Abstract: An encoding module comprises an inverse interleaving module arranged to: determine an initial location index within an interleaving matrix for a data bit; and perform bit reverse ordering (BRO) on a column index value for the initial location index for the data bit to obtain a BRO column index value for the data bit. The inverse interleaving module is further arranged to calculate a number of valid interleaving matrix addresses preceding a location index for the data bit following bit reverse ordering; and determine a position of the data bit within the interleaved data stream based on the calculated number of valid addresses.

  • Device having turbo decoding capabilities and a method for turbo decoding
    Patent number: 8171384
    Abstract: A device and a method for turbo decoding, the method includes performing multiple iterations of a turbo decoding process until a turbo decoding process is completed; wherein the performing comprises repeating the stages of: (i) initializing at least one state metric of multiple windows of a channel data block for a current iteration of the turbo decoding process by at least one corresponding state metric that was calculated during a previous iteration of the turbo decoding process; and (ii) calculating in parallel, at least forward state metrics and backward state metrics of the multiple windows, during the current iteration.
