Consider the SW-ARQ protocol in which the packet size is n bits. Forward Error Correction (FEC) is used to improve the performance. The FEC code employed can correct up to 2 bits in error per packet. In other words, the packet is in error iff the number of error bits during transmission is greater than 2. (a) If the bit error rate is 0.002, and packet size n = 125 bytes, what is the packet error rate? (b) Assume that there is no errors in the acknowledgments, what is the av- erage number of retransmissions for a packet? (c) If the feedback channel also has a bit error rate of 0.001, and the ac- knowledgment packet size is 25 bytes, no FEC code employed for the ac- knowladamante tha hit in in
