Abstract:

Now a day’s all the communication systems are using filters. Some of the case life time of those systems is biting due the error present in the filters. Because the original information is not sent in receiver sides, so the fault tolerant is need for those system. The fault tolerant is achieved by using error correction code (ECC). The filter protection is depends on the fault tolerance. In this paper using raptor code for error detection and correction. The code can detect and correct error and also reduce the density of the sending message. Increase the process speed and low power can be required for process. Implementation cost also low, it gives more protection for the filters. Raptor code is achieved by concatenation of linear code (LT) and pre-code. LT code recovers a large proportion of input symbols. Pre-code recovers the fraction unrecovered by LT code. Raptor code can also use over a noisy channel.

Keywords:

Error correction code (ECC), filter, Binary erasure channel (BEC), LT code, pre-code
