Abstract

Teknologi MIMO digunakan untuk meningkatkan kapasitas sistem dan laju data pada sistem komunikasi wireless dengan memanfaatkan penggunaan space time diversity. Salah satu skema space time yang terkenal pada MIMO adalah skema space time Alamouti. Beberapa modul test-bed telah dibuat untuk mengimplementasikan sistem komunikasi wireless seperti Wireless Open Access Research Platform (WARP). Platform WARP  menawarkan sumber daya untuk mengimplementasikan algoritma nirkabel canggih pada semua layer jaringan. Penelitian ini melakukan perancangan implementasi sistem komunikasi MIMO 2×2 menggunakan skema Alamouti berbasis WARP, simulasi sistem komunikasi MIMO 2×2 Alamouti menggunakan MATLAB serta implementasi sistem komunikasi SISO. Metode pengukuran yang diusulkan pada makalah ini adalah menghasilkan nilaibit error rate (BER) terhadap perubahan jarak antar node (meter) dan kapasitas sistem MIMO Alamouti 2×2 ve sus jarak antar node (meter) untuk MIMO dan nilai BER untuk SISO. Hasil yang telah diperoleh pada penelitian ini adalah simulasi sistem komunikasi MIMO 2x2 menggunakan skema Alamouti menggunakan MATLAB. Hasil dari simulasi berupa grafik perbandingan bit error rate (dB) dan Eb/No serta nilai BER dari implementasi sistem komunikasi SISO.

Abstract

Islam religion has been taught to the students since they are in junior high school, but the juvenile delinquency still often happens. Based on M. Amien Rais, social tawhid is needed to be solution of the problem above. Budi Mulia Dua Yogyakarta International Senior High School is one of many schools that is built by M. Amien Rais which has been doing the implementation of the social tauchid concept. Based on M. Amien Rais, social tawhid means a social dimension from tauh?dull?h (to a knowledge the oneness of God). The implementation of the social tawhid concept of M. Amien Rais in Budi Mulia Dua Yogyakarta International Senior High School could be seen from the arrangement of the perspective an the mission of the school. Then it is applied in extracurricular activity and is evaluated by meeting session. Some of the extracurriculars that apply the social tawhid mission are social volunteer, the distribution of Qurban?s meat, tithe institute and flea market.

Abstract

Wireless Digital Communication System nowadays must have the ability to provide a high data rate and highly reliable QoS. The application of multi carrier system offers a privilege in the spectrum efficiency aspect, because of the possibility of overlapping an orthogonal subcarrier. In MC-DS-CDMA system, some user sutilizing the same broadband frequency at the same time. Each user is distinguished by applying a unique spreading code. The problem is, the code sometimes becomes correlated with each other, hence affecting multi-user interference. This problem depends on the orthogonalities of the spreading codes that is used for each user. In this paper, implementation of MC-DS-CDMA system is done using DSK TMS320C6416T platform that is controlled via matlab simu link. Performance analysis of MC-DS-CDMA system is discussed from the aspect of resulting bit error rate (BER) parameter. Simulation and measurement are conducted to measure the real performance of the MC-DS-CDMA system prototype by giving a variation of the Eb/No value. From the measurement results, it shows a similarity with the expected theoretical result. The best result is obtained when the system operate with Eb/N0≥12dB. And the system failed to for Eb/N0≤4dB.

Abstract

In order to have a reliable and robust data transmission in digital communication system, channel coding is applied for improving the performance of the system. Convolutional code is one of channel coding technique for error detection and error correction. In this paper, convolutional code is used for improving the bit error rate (BER) performance in Quadrature Phase Shift Keying (QPSK)modulation scheme which is implemented on a Wireless Open-Access Research Platform (WARP). Based on implementation and measurement results show that with an equal transmit power (with Tx gain =20dB), QPSK modulation with convolutional code have a lower BER than the uncoded one. For convolutional code with rate =1/2 at a range of 6 meter has a BER value of 0.00065232 while the uncoded BER is 0.0048828. By comparison of the system performance with different coding rate (1/2,2/3,3/4.5/6 and 7/8), the BER performance of QPSK system with convolutional code rate of 7/8 is better that the others. It can achieve a BER of 0.00037495.
