mutually independent and identically distributed,

Assume bit errors are mutually independent and identically distributed, each occurring with positive probability P <<1.

 

a.    Find the even parity bit of the eight-bit message 01101001.

 

b.    Derive the probability of error detection of an arbitrary m-bit message using 1 bit parity, where m is even.

 

c.     Find the two-bit checksum of message 01101001 by simple XOR summation of consecutive two-bit message components.

 

d.    Derive the probability of error detection of an arbitrary 2m-bit message using two- bit checksum of (c). You can apply the answer to (b).

 

e.     Find the CRC of the message 01101001 if the (XOR) generator is 101.
