Abstract

Communication systems (100) will encode and decode. Information using at least four levels of modulation. For sending information as a symbol That represents the symbol bit In the position of the symbol bit At least one symbolic position shows the rate. The higher the error of another location, the processor (204) encodes the information (702) into the number of pairs of code words and sends the code word into an alternated stream. 204) will arrange for a new (706,708) of the delivery order. Bit word code in a predetermined way In order to be held as a modified transmission sequence so that the code word is transmitted (710) with the same error rate, the receiver (110) receives and the demodulation ( 712) Alternate stream In order to make it get a bit of code word. And reorder (714,716) of code word bits in order to undo bit modifications resulting from the modified transmission sequence by storing the new code word. The receiver will decode the code word. In order to recover that information
