摘要： A method and apparatus for encoding and decoding data is described herein. During operation, data enters a convolutional encoder (101). The encoder encodes the information bits from the data at encoding rate (1/R0) to produce data symbols vectors P0, P1, . . . , PR0. Vectors P1, . . . , PR0 are each interleaved separately to form vectors P0′, P1′, . . . , PR0′. A multiplexer (105) multiplexes P0′, P1′, . . . , PR0′ to produce vector Q. The multiplexed interleaved symbols Q are input into symbol adder/remover (107) where appropriate symbols are added or removed to match an over-the-channel transmission rate. Finally, vector Q′ is transmitted via over-the-channel transmission.

摘要： A method and apparatus for interleaving within a communication system is provided herein. More particularly parameters for a convolutional turbo code interleaver are provided, and interleaving takes place utilizing the new parameters. The new parameters generate interleavers that have the correct turbo code behaviors of improving performance with increasing block size and an error floor well below a block error rate of 10−4. Furthermore, the parameters have no implementation impact. Interleaving in accordance with the preferred embodiment of the present invention can achieve a block error rate of 10−4 at a signal-to-noise ratio that is at least 0.5 dB, and in some cases up to 1.3 dB, smaller than that which can be achieved with the code using the existing parameters.

摘要： Decoding signals represented by a trellis of block length N divided into windows of length L includes a step of decoding a backward recursion from a point P that is after the end of a window back to the end of the window. P is chosen at a sufficient distance from the end of the window such that backward recursion determines a known state metric at the end of the window. A next step includes decoding the window using backward recursion from the known state at the end of the window back to the beginning of the window to define a set of known backward recursion state metrics which are stored. A next step includes decoding using forward recursion starting from a known state at the beginning of the window and moving forward. A next step includes calculating a soft output at each stage of the forward recursion using the stored backward recursion state metrics, and branch metrics at each stage, and outputting the soft output for that stage.
