As technology grows error correction schemes also improved in communication system, but still facing some problems in the error detection and correction process. In this paper will discuss the LDPC Encoder scheme in MATLab simulation tool. Low Density Parity Check (LDPC) code is the linear error correcting code used in the spurious environment to correct the error occurring in the message data. We consider the multimedia file as input but we need information in digital form, So we are converting this multimedia file to digital form by using the analog to digital conversion algorithm. Here we use the LLR / Min sum algorithm to produce the LDPC encoding/decoding. This can be achieved by using the Matlab software. Here we can also plot graph of LDPC algorithm with respect to BER and Signal to noise ratio. This shows that implemented LDPC coder have less sensitivity to noise |
