(D. Tse and P. Viswanath, 2005) In 151, the proposed scheme is known as "the diversity of user cooperation," the author of this particular plan to achieve the rate in the region and the probability of failure. Sendonaris, who proposed a simple method of user cooperation, based on a signal of DF with the CDMA scheme. According to Liu (2009), different users with different orthogonal spreading codes can distinguish between different forms of cooperation from users to send information to the recipient. (Liu, 2009) Laneman and other reports, increased data rates and the results achieved in reducing sensitivity to channel change, and concluded that working effectively together to simulate a case of multiple antennas, assistance with single antenna terminals.

The second mode, the user can have a variety of ways. Recognizing the easiest way is by the couple, each corresponding to two users, the other as a partner. Topology does not correspond to other types of constraints can also be used. This indicates the program has the advantage of simplicity and adaptability. (Anghel and M. Kaveh, 2004, pp. 1416-1421)
According to D. Tse and P. Viswanath (2005), signal can be completely decoded by the relay. It takes time to load and bandwidth of the processor. Correct the error or failure, which allows you to adjust the relay station, receives the data bit errors. In this case, the relay can be detected in the received signal with a checksum error. (D. Tse and P. Viswanath, 2005) Another application, including symbols and decodes the signal re-coded to eliminate any delay caused by decoding and processing. It 'also need care cases, have limited computing power relay or transmit sensitive data. (T. Cover, 1979, pp. …show more content…
