- W3090240259 abstract "The combination of multiple input multiple output (MIMO) with orthogonal frequency divisionmultiplexing (OFDM) is one of the main wireless communication technologies for fourth-generation ( 4 G).It has ability to overcome inter symbol interference (ISI) and frequency selective fading of channel, increasesystem capacity and obtain maximum spectral efficiency. Forward error correction (FEC) can be used todetect and correct errors that occur during data transmission, thereby improving the performance of MIMOOFDM. In this paper uses Low Density Parity Check (LDPC) to simulate the performance of the MIMOOFDM system with space time block code (STBC) exploiting the benefits of Maximal Ratio Combining(MRC) over fading channel. Low-density parity check (LDPC) code is one of forward error correction(FEC) codes that can improve system reliability. MIMO-STBC-OFDM and MRC together can be used withLDPC codes for different digital modulation which are binary phase shift Keying (BPSK), Quadrature PhaseShift Keying (QPSK), Quadrature Amplitude Modulation (16-QAM) and (64-QAM) to ensure fairinvestigation. The received signals from several paths are weighted and combined, in accordance with theMRC scheme, and the performance is further maximized by increasing the signal-to-noise ratio (SNR) ofthe MIMO-OFDM system. Results of the simulation show that the suggested MIMO-OFDM system iscombined with STBC-MRC with LDPC (coded) obtain better performance than un-coded MIMO-OFDM ." @default.
