1. A method of reducing memory requirements in a system including at least one deinterleaver and a decoder, said system being constructed and arranged to receive a plurality of symbols for a plurality of channels, said method comprising:

  • making a plurality of buffers in a memory available for receiving said symbols, each of said buffers including a plurality of chunks, each chunk having a minimum of n/x locations, where n represents a number of symbols in a frame period and x represents a number of channels;

    receiving and storing at least a portion of the symbols from the frame period for at least some of said plurality of channels into corresponding ones of said chunks, each of said corresponding ones of said chunks storing symbols of only a corresponding one of said channels;

    decoding said symbols received during frame periods for said at least some of said plurality of channels after said symbols are stored into said chunks during complete ones of said frame periods; and

    making said chunks, which store said decoded symbols, available for receiving additional symbols.
