Chapter 1, Problem 54CRP

a.

Explanation of Solution

Decode the message 111010110110:

Hamming Distance:

The hamming distance between two bit patterns is the number of bits in which the patterns differ.

An error correcting code is,

SymbolValue represented
A000000
B001111
C010011
D011100
E100110
F101001
G

b.

Explanation of Solution

Decode the message 101000100110001100:

Compare each pattern with the patterns in the code of table 1 until that pattern is found which is within a distance of one from the received pattern.

  • The pattern 101000 matches with F of table 1 because 101000 and 101001 differ by one hamming distance

c.

Explanation of Solution

Decode the message 011101000110000000010100:

Compare each pattern with the patterns in the code of table 1 until that pattern is found which is within a distance of one from the received pattern.

  • The pattern 011101 matches with D of table 1 because 011101 and 011100 differ by one hamming distance.
  • The pattern 000110 matches with E of table 1 because 000110 and 100110 differ only by one hamming distance

d.

Explanation of Solution

Decode the message 010010001000001110101111000000110111100110:

Compare each pattern with the patterns in the code of table 1 until that pattern is found which is within a distance of one from the received pattern.

  • The pattern 010010 matches with C of table 1 because 010010 and 010011 differ by one hamming distance.
  • The pattern 001000 matches with A of table 1 because 001000 and 000000 differ only by one hamming distance.
  • The pattern 001110 matches with B of table 1 because 001110 and 001111 differ only by zero hamming distance.
  • The pattern 101111 matches with B of table 1 because 101111 and 001111 differ only by one hamming distance
