The matrix-based MATLAB language is the world's most natural way to express computational mathematics. It doesn't begin to save space on the encoding until some of the symbols are at least twice as probable as some of the others or at least half the potential symbols are never unused, which are situations that would allow it to save 1 bit per occurrence. The transmitter sent out a single signal through one antenna, which eventually arrived at a single antenna at the receiver, probably along with a little noise. Code specific design ¾Different H matrix structures give different interconnections Large amount of memory consumption Requirements: A single decoder for a broad class of codes ¾Column weight, code rate, block length, H matrix structure Fit the decoder in a single FPGA High throughput.
