چکیده
Wireless transmissions can be significantly affected by influences from its surroundings, which are most commonly expressed in a form of error probability statistics. IEEE 802.15.4 wireless personal area networks (WPANs) use Direct Sequence Signal Spreading (DSSS) technique in order to be able to operate together with other types of wireless networks in 2.4GHz band. By use of DSSS, IEEE 802.15.4 transceivers are able in some level to cancel out interference from other types of networks. Such interferences have same influence as background noise and are most commonly modeled as Additive White Gaussian Noise (AWGN). This work presents mathematically based chip error probability model of IEEE 802.15.4 wireless communication in presence of AWGN. Presented results for theoretical chip error rate model are confirmed by simulation of IEEE 802.15.4 transmission through AWGN channel according to Monte Carlo method.
