Hamming Code
Sixteenbit messages are transmitted using a Hamming code. How many check bits are needed to ensure that the receiver can detect and correct singlebit errors? Show the bit pattern transmitted for the message 1101001100110101. Assume that even parity is used in the Hamming code. My Solution: But Correct answer is : 011110110011001110101 I don't know what i am doing wrong ?

hamming distance
To provide more reliability than the Single Parity Bit technique, a new errordetecting scheme has been proposed. The scheme uses first parity bit for checking all the odd numbered bits and a second parity bit for all the even numbered bits. What is the (minimum) Hamming distance of this code ?
