Hi,

For a channel with a BER (Bit Error Rate) the probability to have the
error flag set is a function of the "length" of the transmitted packet.
But for the PER (Packet Error Rate) I assume that the error flag setting
is only a function of the number of "packets" passing through this
channel (independantly of the size of the packet)... is this correct ?

Yes, this is true. Basically, it generates an r=[0,1) random number for each
packet, and if r<PER, then it sets the error flag on the packet.
