4. Conclusions

This paper investigated influence using the DS-CDMA with minimum energy (ME) coding for the wireless sensor networks. The achieved results show that the ME DS-CDMA reduce the multiple access interference, save amount of power and improving the system performance; with sending a high bit rate, 1's, the probability of multiple access interference is highly decreases with utilizing the MAI, when a certain probability of multiple channels transmitted signals and identical time are kept. This leads to enhance the total performance of the system. The ME DS-CDMA is important to be chosen for wireless sensor network due to its important role in improving the probability of bit error rate and SNR for saving power with

various number of users (receivers).
