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

, in most wireless scenarios, the BER is assumed to be 10^-6. By the way, why are you posting this in ns-users list? Abdul. 林泰邑 wrote: for example : when I give ber=10^-3, packet size=1000bytes, what is PER? -Original Message- From: Abdul Jabbar [mailto:[EMAIL PROTECTED] Sent
