- Abstract
- Combining OFDMA with MIMO is the key technology for the 4G mobile communication. OFDMA can relieve inhernet difficulties of high-speed transmission. MIMO technology can be largely categorized into two techniques: ibe us STC fir duversity gain and the other is SM for high frequency efficiency, In this paper, we deouct various MIMO techniques of two tranmit antenna and compare the computational complexity of decoding process for the techniques. Then, we analysis the performance of the techniques in the WiBro downlink environment based on OFDMA. We perfer ML algorithm which is the optimum performance and ZF algorithm of least computational complexity for SM detection.
