Abstract

Negara Indonesia terdiri dari ribuan pulau yang terbentang dari Sabang hingga Merauke. Namun di saat teknologi telekomunikasi berkembang dengan sangat pesat masih terdapat banyak daerah yang kesulitan dalam mengakses informasi.. High Frequency (HF) merupakan sistem komunikasi menggunakan gelombang radio yang bekerja pada frekuensi 3-30 MHz dengan panjang gelombang 1-10 m. HF biasanya digunakan untuk radio komunikasi jarak jauh karena sifat gelombangnya dapat dipantulkan oleh lapisan ionosfer, yakni mampu mengirimkan sinyal 80 km sampai dengan 600 km di atas permukaan bumi,sehingga dapat menjangkau tempat yang jauh tanpa menggunakan repeater. Di zaman ini dimana laju data berperan penting dalam perkembangan informasi, dibutuhkan metode baru guna meningkatkan laju data yang diperlukan di kehidupan sehari-hari. Sistem Komunikasi HF dengan menggunakan metode MIMO 2×2 merupakan salah satu alternatif yang cocok, terutama di wilayah indonesia yang masih tertinggal. Pada sisi pemancar dan penerima masing masing memiliki 2 antenna untuk metode Multi Input Multi Output (MIMO) untuk proses pengukuran di lokasi Surabaya-Malang dan Bandung-Surabaya. Proses evaluasi kinerja sistem komunikasi HF dengan skema Alamouti dapat memperhitungkan Kapasitas kanal sebagai parameter utama. Didapatkan bahawa terjadi peningkatan nilai kapasitas sebesar dua kali lipat. ============================================================================================================ Indonesia consists of thousands of islands stretching from Sabang to Merauke. However, when telecommunications technology is developing very rapidly there are still many areas that have difficulty in accessing information. High Frequency (HF) is a communication system using radio waves that work on a frequency of 3-30 MHz with a wavelength of 1-10 m. HF is commonly used for long-distance radio communications because the wave properties can be reflected by the ionosphere layer, which is capable of transmitting 80 km to 600 km above the earth's surface, thus reaching far away without repeater. In this day and age where data rates play an important role in the development of information, new methods are needed to increase the rate of data needed in everyday life. HF Communication System using MIMO 2 × 2 method is one of the suitable alternative, especially in Indonesia which is still lagging behind. On the transmitter and receiver side, each has 2 antenna for Multi Input Multi Output (MIMO) method for measuring process at Surabaya-Malang and Bandung-Surabaya location. The process of evaluating the performance of HF communication system with Alamouti scheme can take into account the channel capacity as the main parameter. It was found that there was a doubling in the value of capacity.
