In this paper we proposed the comparison of DF (decode and forward) model of cooperative diversity with CRC (cyclic redundancy check) and without CRC. From the comparison, we find that in the low SNR (signal to noise ratio) range, that the DF without CRC is better than the DF with CRC, in the high SNR range, the result is reverse. According this result, we can propose the adaptive switch method between CRC and without CRC based on the SNR of each branch. (3 pages)
