Unformatted text preview: ECEN 455 Lab 5: Binary Linear Codes Due Tuesday 11/23/10 Overview: This exercise will introduce the concept of linear codes used to protect transmitted data from errors caused by noise in the environment. First, we will use a simple code defined by P = 1 1 0 0 1 1 1 0 1 with generator matrix G = [ P,I 3 ] and parity-check matrix H = [ I 3 ,- P T ] . Later, we will use the (23 , 12) Golay code, which is closely related to the code used on the original Voyager space probe. It has generator matrix G = [ Q,I 12 ] and parity-check matrix H = [ I 11 ,- Q T ], where the matrix Q can be found in golay.mat file and is given by Q = 1 1 0 0 0 1 1 1 0 1 0 0 1 1 0 0 0 1 1 1 0 1 1 1 1 1 0 1 1 0 1 0 0 0 1 1 1 1 0 1 1 0 1 0 0 0 1 1 1 1 0 1 1 0 1 1 1 0 1 1 0 0 1 1 0 0 0 1 1 0 1 1 0 0 1 1 0 0 0 1 1 0 1 1 0 0 1 1 1 1 0 1 1 1 0 0 0 1 1 1 0 1 0 1 0 0 1 0 1 1 1 0 0 1 0 0 1 1 1 1 1 1 0 0 0 1 1 1 0 1 0 1...
