Abstract: |
MIMO-OFDM system with detectors Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) is used to eliminate fading and using convolutional code that can help the performance of channel coding in order to work optimally. This coding technique is expected to generate a low BER curves. MIMO-OFDM based on single Radio frequency (RF) has the function to efficiency power consumption. In a previous study discusses the performance of MIMO-OFDM system based on single RF, the result that a single RF antenna symbol rate may change periodically and does not require a high power consumption. Computer simulation results shows that channel estimation in MIMO-OFDM system based on single RF working properly shown by the curve magnitude and phase, showing the performance of MIMO-OFDM system based on single RF with some parameters such as detectors, modulation, convolution code on the curve BER on the SNR. |
