Abstract

Sistem komunikasi High Frequency (HF) digunakan untuk melakukan komunikasi jarak jauh dengan memanfaatkan pantulan pada lapisan ionosfer. Sistem komunikasi HF dapat menjangkau tempat yang terisolasi dan berfungsi sebgai sistem komunikasi alternatif saat terjadi keadaan darurat seperti bencana alam. Sebagai sistem komunikasi alternatif, Sistem komunikasi HF diharuskan dapat mengirimkan data informasi dalam jumlah besar melalui kanal HF. Untuk mendukung kemampuan tersebut, maka digunakanlah sistem Multiple Input Multiple Output (MIMO). Sistem MIMO menggunakan lebih dari satu antena pada kedua transmiter dan receivernya untuk meningkatkan kapasitas kanal. Sistem MIMO memiliki keunggulan yaitu pengiriman data yang lebih cepat dibandingkan dengan sistem Single Input Single Output (SISO). Sistem HF MIMO kemudian digunakan pada Kanal HF Multimode. Kanal HF Multi-mode merupakan kanal dimana glombang sinyal HF dipancarakan menuju lapisan Ionosphere kemudian dipantulkan kembali ke bumi dalam beberapa lintasan. Akibat pantulan tersebut, gelombang sinyak HF yeng semula berpolarisasi linear terpecah menjadi dua mode sinyal yaitu O dan X dengan arah polarisasi berbeda. Dengan menggunakan kanal ini sinyal menjadi tahan teterhadap redaman. Penelitian mengenai kanal HF multimode sudah pernah dilakukan, namun belum dilakukan evaluasi mengenai kapasitas kanal dan laju kesalahan yang menggunakan sistem MIMO. Evaluasi dari kapasitas kanal diharapkan dapat memberikan informasi mengenai kapasitas yang dapat digunakan dalam sistem MIMO 2x2 dan Penelitian Laju kesalahan dapat digunakan untuk mengukur keakurasian data yang diterima oleh penerima. ================================================================================================ High Frequency (HF) communication system is used for long-distance communication by utilizing reflections in the ionosphere layer. The HF communication system can reach isolated places and function as an alternative communication system in the event of an emergency such as a natural disaster. As an alternative communication system, the HF communication system is required to be able to transmit large amounts of information data through the HF channel. To support this capability, the Multiple Input Multiple Output (MIMO) system is used. MIMO systems use more than one antenna on both the transmitter and receiver to increase channel capacity. The MIMO system has the advantage of faster data transmission compared to the Single Input Single Output (SISO) system. The HF MIMO system is then used on the Multimode HF Channel. Multi-mode HF channel is a channel where HF signal waves are emitted to the Ionosphere layer and then reflected back to the earth in several paths. As a result of this reflection, the HF signal wave which was originally linearly polarized is split into two signal modes, namely O and X with different polarization directions. By using this channel the signal becomes resistant to attenuation. Research on multimode HF channels has been carried out, but no evaluation has been carried out on the channel capacity and error rate using the MIMO system. The evaluation of the channel capacity is expected to provide information about the capacity that can be used in a 2x2 MIMO system and the Error rate Research can be used to measure the accuracy of the data received by the receiver
