PERFORMANCE IMPROVEMENT OF OFDM TRANSMISSION USING AMC AND DIFFERENT MIMO TECHNIQUE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 3
Abstract
In the rapid growing field of wireless communications, there is an increasing demand of higher rates with longer transmission ranges for new broadband applications. It was a big challenge for modern wireless communications networks to provide services like video, voice, data including mobility. The project presents the analysis of SpaceTime Block Codes used for Multiple-Input Multiple-output MIMO-OFDM technology is a combination of multipleinput multiple-output antenna technology with orthogonal frequency division multiplexing. Adaptive modulation schemes for fading channels are usually required to fulfill certain long-term average error rate targets. The error rate level is depend on the modulation type, SNR value and channel behavior. To transmit the faithful data over these systems the error rate performance is further improved using forward error correction codes (FEC). Error rate performance is evaluated for these codes under different modulation schemes like QPSK, BPSK, and QAM techniques.
