System and method for decoding punctured subframes. A preferred embodiment comprises a first deinterleaver unit (for example, 5-ms deinterleaver) and a second deinterleaver unit (for example, 20-ms deinterleaver) operating in parallel, deinterleaving one symbol stream using 5- and 20-ms duration frame formats, for example. After the reception of each 5-ms subframe, the subframe is decoded in a decode unit (for example, rate matching, decoding, and CRC checking (RDC) unit) to verify that the subframe contains 5 ms duration frame data. If so, the subframe is noted. If all 5-ms subframes in a 20-ms duration frame contain 5-ms duration data, no decoding of results by the second deinterleaver unit is needed. If the entire 20-ms duration frame is not all 5-ms duration data, then the 5-ms duration data subframes are zeroed and the remaining data is decoded as 20-ms duration data.

Method and apparatus for decoding punctured subframes

System and method for decoding received information using batched processing of independent parameters. A preferred embodiment comprises a decoder (for example, decoder) with a memory (for example, memory) that may be partitioned into a plurality of parts, one of which being a parameter partition (for example, parameter partition). A digital signal processor (for example, DSP) programs the decoderwith various ways that it wishes received data to be decoded and the decodercan operate independent of the DSP, storing the results of each decoding operation in a specified location. At specified instances, the decoderinterrupts the DSPto allow the DSPto retrieve the decoding results.
