Question: a Suppose a receiver using the CRC generator polynomial x 4 + x 2 + 1 receives the sequence of bits 0 1 0 0

a Suppose a receiver using the CRC generator polynomial x4+x2+1 receives the sequence of bits 010010101101. Were they received correctly? If so, what was the transmitted message? If not, can you tell how many bit errors occurred? Show your work.
b Could the above generator detect any odd number of bit errors? Why or why not?
c Recall that nodes in slotted-ALOHA transmit in each slot with probability p. Suppose that a given channel has exactly 8 nodes. What is the probability that there is a collision in a given slot?
