摘要： A system (12) for determining discrete transforms as between time and frequency domains. The system comprises a grid (60) comprising adders and multipliers. The grid is operable to perform in parallel an integer number P operations of a first transform function selected from one of either an IFFT or an FFT. The system also comprises the integer number of P serially-operating pipelines (641-648). Each of the pipelines is coupled to the grid and is operable to perform serially over a number of cycles an integer number S operations of the first transform. In the system, S and P are both greater than one and, in combination, the grid and the serially-operating pipelines perform the first transform type as an S×P-point transform. In a first instance at least a portion of the grid is operable to perform IFFT operations. In a second instance at least a portion of the grid is operable to perform FFT operations.

摘要： A de-interleaver-de-puncturer architecture is scalable and capable of achieving a higher data throughput than that achievable using a conventional disjointed de-interleaver-de-puncturer architecture. The higher data throughput is achieved without increasing the clock speed of the de-interleaver. The scalable de-interleaver-de-puncturer architecture is also less complex than a conventional disjointed de-interleaver-de-puncturer architecture.
