Performance Analysis of a Broadband MISO/OFDM Transmission System

In this paper, we propose a broadband MISO/OFDM transmission system with adaptive bit and power allocation. The model of proposed system is established. The performance of maximal SNR on each sub-carrier of proposed system is analyzed. The simulation results show that the proposed system can achieve better performance compared with that of the conventional adaptive transmit diversity based OFDM systems without adaptive bit and power allocation over multipath fading channels.
