Performance Evaluation of Image Transmission Over Sparse MIMO-OFDMA System with Antenna Diversity Scheme
Taranjeet Singh Huda and Rahul Sharma
The Sparse Multiple-Input Multiple-Output based Orthogonal Frequency Division Multiple Access (MIMO-OFDMA) is a promising high data rate interface technology. MIMO channel can offer a significant gain over a traditional single input single output network. In this paper, an overview of MIMO-OFDMA will be given, for maximizing the overall system capacity. Antenna selection is realized to enhance overall data rate based on MIMO channel estimation. Adaptive M-QAM modulation is performed on selected antenna on each subcarrier.
