Linear Block Codes
		n Check the previous code to see that it consists of block of code words. Your message will be changed to this format. n Add any two code words to get a third one. n A code with dmin is ‘guaranteed’ to correct (dmin – 1) / 2 errors or detect dmin – 1 errors. n dmin = wmin (the smallest weight of the nonzero code word. n Any linear block code can be systematic:
			n-k check bits		k information bits
