To encode the message, multiply by an invertible matrix A. Write the coded message in a 3x6 matrix, adding 0's for blanks. Calculate the product using a graphing calculator. [7-3-31「13 18 5 1...
1. Channel Coding We would like to add linear block code (3,6) using the generator matrix: 1 001 01 G-0 1 0 0 1 1 (a) (5 points) Determine the parity check matrix H (b) (20 points) What is the minimum distance of this code? How many error can this code correct? (c) (5 points) What is the code word for the data sequence 011000101111? (d) (20 points) If you receive the codeword 010001000010101010, what is the transmitted sequence?
PARITY CHECK MATRIX DECODING 1. The affine cipher y 21x + 11 (mod 26) was used to encode a message. Each resulting letter of the ciphertext was converted to the five-bit string consisting of the base-two equivalent of the value of the letter. The systematic (9,5) linear code with standard generator matrix G given by [1 0 0 0 0 1 0 0 11 To 1000 1100l G= 0 0 1 0 0 1 1 1 1 0 0 0...
