ABSTRAK
Kanal (saluran transmisi) digital sangat rentan dipengaruhi oleh noise, distorsi,
dan interferensi, sehingga output kanal yang ditransmisikan akan berbeda dari
input kanal, akibatnya akan timbul kesalahan (error) pada data. Oleh karena itu,
dibutuhkan teknik pengkodean untuk mengatasi hal tersebut. Teknik pengkodean
dirancang agar mampu mengkoreksi kesalahan (error) pada proses transmisi
sehingga diperoleh data sesuai dengan yang dikirimkan. Pada Tugas Akhir ini
disimulasikan suatu sistem yang dapat mengubah suatu data (pesan) menjadi kode
BCH, mendeteksi dan memperbaiki bit error. Kode BCH dirancang agar mampu
memperbaiki bit error (t) sebanyak - banyaknya tiga, panjang kode dan panjang
data (n,k) sebanyak: (15,5), (31,16), (63,45), (127,106), (255,231), dan pada
proses pendekodean digunakan algoritma Berlekamp. Sistem telah berhasil
direalisasikan sesuai yang direncanakan.

ABSTRACT
Digital channels are often to get vulnerable against noise, distortion, interference.
Therefore, the output of channels may be different from the input and it produces
error on received data. In order to solve that, coding technique is needed. Coding
technique is designed to provide error corrector in transmission so that the correct
message can be obtained. This final project is a simulation of how to generate
BCH code, adding error to the codeword, detection the error and how to repair it.
This BCH code is designed to repair 3 errors (t) at most, code length and data
length (n,k) : (15,5), (31,16), (63,45), (127,106), (255,231), and uses Berlekamp
algorithm on the decoding process. The coding and decoding system has been
successfully created.
