Abstract

Komunikasi bergerak selular adalah suatu komunikasi antara dua terminal di mana salah satu atau kedua terminal tidak berada pada lokasi atau posisi yang tetap, misalkan komunikasi yang dilakukan oleh orang yang sedang dalam perjalanan. Keberadaan system radio selular adalah karena kebutuhan akan tersedianya pelayanan telepon bergerak dalam jangkauan nasional bukan hanya untuk daerah tertentu saja. Sistem komunikasi selular membagi wilayah pelayanan yang akan dijangkau menjadi bebrapa zona-zona kecil yang disebut sel, setiap sel dilayani oleh suatu Base Station. Kelebihan sistem selular bila dibandingkan dengan sistem konvensional adalah adanya fasilitas Handoff, di mana pembicaraan tidak terputus bila pembicaraan berpindah sel. Hal ini terjadi karena kanal sel yang digunakan akan berganti secara otomatis. Dari permasalahan di atas maka diperoleh suatu ide untuk membuat suatu program yang mampu mensimulasikan proses pencarian jalur komunikasi (routing) pada jaringan telekomunikasi, dan program yang dibangun ini diharapkan akan memberikan pemahaman mengenai routing (proses pencarian jalur komunikasi. Untuk menghindari kekeliruan pada proses pencarian rute atau kegagalan pencarian maka dalam proses algoritma gentika harus diinisialisasikan dengan benar.Kata Kunci— Algoritma Genetika.

Abstract

Jaringan Optical Wireless adalah sistem komunikasi yang memanfaatkan frekuensi cahaya sebagai media transmisinya, dengan menggunakan daerah frekuensi infra merah sebagai panjang gelombang. Dalam optical wireless, informasi dikirim menggunakan media udara melalui cahaya optik, umumnya digunakan dalam jarak yang relatif pendek, dan tentu saja sangat dipengaruhi oleh keadaan cuaca, adanya sinar matahari, petir, lampu atau cahaya yang memiliki panjang gelombang pada daerah infra merah. Kondisi yang mengganggu ini akan sangat mempengaruhi kualitas transmisi data dan informasi, apalagi jika jarak transmisi sinyal semakin jauh. Interferensi dapat menyebabkan kesalahan pada bit-bit sinyal yang dikirimkan, sehingga penerima atau penerima akan menerjemahkan sinyal tersebut menjadi bentuk data dan informasi yang berbeda. Metode : probabilitas error rate yang dipengaruhi oleh faktor transmisi yaitu jumlah user, bobot kode biner, panjang kode, jumlah bit data, probabilitas rate dan juga faktor peningkatan kecepatan. Penelitian ini bertujuan untuk menganalisis performansi Probability of Bit Error Rate pada sistem komunikasi optik nirkabel menggunakan OOK-CDMA dan PPM-CDMA. Hasil menunjukkan bahwa Probability of Bit Error atau Bit Error Rate pada PPM-CDMA memberikan performansi yang lebih baik dibandingkan OOK-CDMA.
