Abstract:
1. A signal processing apparatus for processing Orthogonal Frequency Division Multiplex (OFDM) symbols, the apparatus comprising: a memory architecture including a plurality of memory banks; a demodulation block configured to receive samples of the OFDM symbols and accumulate the samples into a plurality of interlace memory within the memory architecture, wherein the demodulation block comprises: a computational block configured to perform a frequency domain transform on at least one of the samples in the plurality of interlace memory; and a channel estimator coupled to the memory architecture and configured to determine a channel estimate based at least in part on samples accumulated in one of the plurality of interlace memory, wherein the channel estimator comprises a descrambler configured to descramble a plurality of pilot interlace samples stored in one of the plurality of interlace memory.
