Integer codes are very flexible and can be applied in different modulation schemes. A soft decoding algorithm for integer will introduced. Comparison of symbol error probability (SEP) versus signal-to-noise ratio (SNR) between hard using coded shows us that we obtain at least 2dB coding gain. Also, shall compare our results with trellis (TCM) because their similar schemes complexity.
