Sys. Engineering Problem Set No.7 Date Issued April 8 2003 Date Due April 15 2003 Problem 1 Find the capacity for the channel shown in figure 1. This channel is known as a binary erasure channel where with probability a transmitted bit is erased and the received cannot determine if it was a zero or a one. 1-e E 1-E Problem 2 Generate the standard array for the following 6 3 code in systematic form 000000 100101 001011 101110 010111 110010 011100 111001 . How would you decode the received sequence 111111 Problem 3 The generator matrix for a 6 3 code is given above. A find the minimum distance for the code B Find the parity check matrix for the code C What codeword would you use to encode 111 D Suppose you receive 111111 how would you decode it
