Bit stream structure, Computer Networking

Assignment Help:

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

248_Bit stream structure.png

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;

typedef struct {

          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 ]
