Estimating the term…
Multiple channels of received data are processed by a multiple channel demodulation and error correction decoding engine. The statistical uncertainty of processing channels with an iterative decoder are averaged across all the channels to reduce the total processing power required of the decoding engine compared to processing each channel with a separate engine. A set of input buffers holds blocks of data for each channel needing decoding. A quality measure is computed on each input block to set the priority and iteration allocation of decoding in the common decoder. The input RF signal is digitized by a broadband tuner that processes some or all of the channels to feed the multiple channel demodulator and decoder. Multiple decoded video data streams are output.
A method of processing a plurality of coded channels with error correction coding, the method comprising:
The method of Claim Error! Reference source not found., wherein scheduling includes determining whether some streams can be excluded from the decoding based on the maximum number of iterations calculated for at least one stream.
The method of Claim Error! Reference source not found., further including selecting the plurality of channels using a plurality of broadband tuners, wherein the number of such broadband tuners is less than the number of selected channels.
The method of Claim Error! Reference source not found., wherein the stream having the highest SNR is decoded first.
A multi-channel iterative decoder for processing data from a plurality of channels, comprising:
A multi-channel iterative decoder for processing data from more than one communication channel, comprising:
A multi-channel iterative decoder for processing data from a plurality of communication channels comprising:
