In OSI 7 layer model, a header, or possibly a trailer, can be added to the data unit at each layerI 7 layer, but we will define a simple virtual packet which contains only 8bit data value without any header and trailer
Each packet contains one pixel information of the lenna256 image. We defined the 3 structures in "CPacketStruct.h" to express a packet as bit stream. Left structure is defined for bit stream for error detection code and right structure is defined for bit stream for error correction code. There is additional bit stream without any code, and the data structure of bit stream with no code is same as the Packet structure in "CPacketStruct.h"
typedef struct {
BIT dat1[5];
BIT dat2[5];
} EDBitStream;
BIT dat1[7];
BIT dat2[7];
} ECBitStream;
Fig. Bit stream structure
One pixel data is represented with 8 digits, and each 4 digits are divided into dat1, and dat2. In bit streams for error detection
Ex) 1 Pixel data = 100010012
Normal Packet
(Packet is not encoded)
Encoded Packet by Parity Bit
Encoded Packet by hamming code
[1000 1001]
[Pixel Data ]
[10001 10010 ]
[ (1000)+Parity || (1001) +Parity ]
[1101000 0111001 ]
[ (1000)* G || (1001) * G ]
