摘要： In orthogonal frequency division multiplexing systems, iterative maximum likelihood channel estimation and signal detection is preformed. The channel estimation gives the maximum likelihood estimates of time domain channel parameters. A cost function is defined. An iterative process estimates a joint channel impulse response and a transmitted signal that minimize the cost function, and thus solves the channel estimation and signal detection problem jointly without having specific knowledge of the channel.

摘要： A MAP decoder, or a turbo decoder having constituted MAP decoders, is configured with bi-directional sliding windows. A sliding window architecture is applied to the forward state metric (FSM) calculation of an encoded data block having a trellis with N time-steps. The data block is divided into smaller sub-blocks and a forward recursion of two or more of the sub-blocks are performed in parallel to obtain FSMs. Each sub-block overlaps with a previous sub-block by k time-steps, where k is an integer value greater than zero. This provides a good approximation of the FSMs at time-step k+t of the sub-block. The FSMs associated with the first k time steps of each sub-block, other than the first sub-block, are discarded. A reverse recursion of each sub-block is also performed to obtain reverse state metrics (RSM) for the sub-block. Likelihood ratios are then calculated based on the FSMs and RSMs.

摘要： At least one aspect of the invention provides a turbo encoder having parallel first and second constituent encoders and an interleaver coupled as an input to the second constituent encoder to provide a permutated version of the binary data input to the first constituent encoder to achieve a low frame error rate. The interleaver is configured to parse the binary data input into an input block, determine a permutation vector, and rearrange the order of the binary data in the input block according to a set of predetermined permutation equations. The rearranged binary data in the information block is then passed to the second constituent encoder to improve the distance spectrum of the transmitted redundant data.
