Single-Bit Error mainly occurs in Parallel Data Transmission. For example, Sender sends the data at 10 Mbps, this means that the bit lasts only for 1 ?s and for a single-bit error to occurred, a noise must be more than 1 ?s. Single-Bit Error does not appear more likely in Serial Data Transmission. In the above figure, the message which is sent is corrupted as single-bit, i.e., 0 bit is changed to 1. The only one bit of a given data unit is changed from 1 to 0 or from 0 to 1. Types Of ErrorsĮrrors can be classified into two categories: An Error is a situation when the message received at the receiver end is not identical to the message transmitted. SOME REAL CODE NOWĭata File for VRC - 0100110 1110001 1100101 0000000 //Each line contains one set, called as a Frame.When data is transmitted from one device to another device, the system does not guarantee whether the data received by the device is identical to the data transmitted by another device. Either print the temporary result or adjust any variable. Using the most basic computer filtering mechanism if-else, filter out the processed data of the “res” object. Processing the dataĬonverting each unit of data into an integer and calculating the result(obj : res) according to our requirements i.e. The getline() function on top of a while loop extracts all the data line-wise and stores it in the local data array val. The basic steps into which I have divided the whole program are. It would help us create the link to our local variables upon which the algorithm or the operation would be executed.

Here is how I combined every part to get the results -Īs we are dealing with some sort of data-storage(Text file in my case), we must know the arrangement and organization of the data in it.

For odd parity, this bit is set to 1 or 0 such that the no.

For even parity, this bit is set to 1 or 0 such that the no.

The parity bit can be set to 0 and 1 depending on the type of the parity required. Parity check or Vertical Redundancy Check (VRC) method data + error check bits), receiver is capable of detecting errors in the frame.

Error detection can be made possible by adding redundant bits in each frame during transmission.

Once the error is detected, receiver informs the transmitter to re-transmit the same frame again.

Error detection techniques help in detecting errors in a received block or frame by the receiver.

When a frame is transmitted from a transmitter to the receiver, there are two possibilities, either the frame is received without error or its received with error (bad frame). It was something real which made it kind of interesting for me, hence I thought of sharing it with you guys. This started as an assignment of my DCN(Data and Communication Networks) lab to write a program(in C++) to add parity bit to carry out VRC and LRC on data stored in a text file in binary format.
