Abstract: One embodiment is an apparatus having a memory, a controller, and a de-interleaving module. The memory is configured to store portions of a set of interleaved values, where the set of interleaved values correspond to a single application of an interleaving mapping to a set of un-interleaved values. The controller is configured to retrieve each portion from an other memory that stores the set of interleaved values by moving the portion from the other memory to the memory. The de-interleaving module is configured to de-interleave the interleaved values in at least one of the portions to generate a de-interleaved portion such that processing downstream of the de-interleaving module can begin processing the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module.

Abstract: A method and system for canonical channel estimation in the Long Term Evolution uplink where a multi-frequency signal is generated and then converted to frequency spectrum which is then convolved in the frequency domain with a truncated window function to obtain a time domain channel impulse response. The time domain channel impulse response can be then transformed to a frequency domain to produce a down sampled user channel response, which can be then linearly interpolated to provide a channel estimate for a plurality of subcarriers. Such an approach achieves channel estimation within Long Term Evolution at only canonical locations to reduce complexity without loss in channel entropy.
