چکیده
With the increase in radio communication devices and shared frequency spectrum between these devices, it is critical to neglect the effect of interference on wireless communications. In this paper, we have present the mathematical model of distribution of network interference. For a flexible and accurate representation, interference is modeled by alpha-stable distribution function and we have estimated the values of parameters of alpha-stable distribution depending on total number on nodes in specified area in the network. This allows the better estimation of wireless channel conditions. We have analyzed the bit error rate (BER) and packet error rate (PER) performance of Orthogonal Frequency Division Multiplexing (OFDM)based communication system by varying the total number of nodes in wireless sensor network (WSN). We have also integrated a PHY layer based on Orthogonal Frequency Division Multiplexing (OFDM) in the CupCarbon simulator with the consideration of impulsive network interference.

Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
