for example : when I give ber=10^-3, packet size=1000bytes, what is PER? -----Original Message----- From: Abdul Jabbar [mailto:[EMAIL PROTECTED] Sent: Monday, October 02, 2006 6:24 PM To: 林泰邑 Cc: ns-users@isi.edu Subject: Re: [ns] how do i transfrom "Bit Error Rate" to "Packet Error Rate"? As far as I know, the relationship between BER and PER , assuming that bit errors are independent and uniformly distributed is, PER=1-(1-BER)^N where N is the number of bits. However, the above formula is only approximate because in real life scenarios, the bit errors are not completely independent but may occur in bursts. Further, the error distribution is also not exactly uniform. Hope it helps....
