Description: decoder of Hamming
Use a [7,4] Hamming code.
m = 3 n = 2^m-1 k = n-m
parmat = hammgen(m) Produce parity-check matrix.
trt = syndtable(parmat) Produce decoding table.
recd = [1 0 0 1 1 1 1] Suppose this is the received vector.
syndrome = rem(recd * parmat ,2)
syndrome_de = bi2de(syndrome, left-msb ) Convert to decimal.-decoder of Hamming

Description: In this assignment you will be designing a chip that both encodes and decodes a data stream using a Hamming code. You will also inject random errors into the data stream and your decoder must be able to fix single-bit errors. Note: This project is intended to be individually. I don’t have a problem if you wish to
discuss the project with other students however your final work must be your own.
2. Functional Specification
The chip has to implement the following functions: a) Encode a byte of data using 4-parity bits using a Hamming function b) Decode data using Hamming function, perform error correction -In this assignment you will be designing a chip that both encodes and decodes a data stream using a Hamming code.
