The channel bit error rate is 0.1, and each packet’s total length is 1024 bytes including all overheads. assume there are no other overheads. for each data packet transmitted over the wireless channel, what is the packet error rate (per) for each single round of packet delivery? if one arq retry is applied, (i. e. total rounds of transmissions are 2, including 1 initial transmission, and 1 additional retry), what is the final average probability of packet error?
