Error Detection and Correction Techniques
Aim: a. Write a program for Error Detection usinng CRC. b. Write a program for Error C orrection using Hamming Code. Apparatus (Software): Eclipse/ Netbeans Procedure: Following should be studied to understand this practical Introduction Environmental interference and physical defects in the communication medium can cause random bit errors during data transmission. Error coding is a method of detecting and correcting these errors to ensure information is transferred intact from its source to its destination. Types of errors These interferences can change the timing and shape of the signal. If the signal is carrying binary encoded data, such changes can alter the meaning of the data. These errors can be divided into two types: Single-bit error and Burst error. Single-bit Error The term single-bit error means that only one bit of given data unit (such as a byte, character, or data unit) is changed from 1 to 0 or from 0 to 1 as ...
