Multiple-input multiple-output (MIMO) radar has been receiving increasing attention
in recent years from researchers, practitioners, and funding agencies. MIMO radar is
characterized by using multiple antennas to simultaneously transmit diverse (possibly
linearly independent) waveforms and by utilizing multiple antennas to receive the
reflected signals. Like MIMO communications, MIMO radar offers a new paradigm
for signal processing research.

针对在信道中实时分配比特和功率的问题.采用了一种由Fischer算法改进的自适应算法.经在MATLAB仿真平台下模拟验算比较.结果表明:改进的Fischer算法运算复杂度低,能够根据子载波信道增益大小分配比特.与8PSK固定调制方式MIMO-OFDM系统相比,更能够在保证系统信道质量所需误码率和总发射功率前提下,根据信道状态信息,动态分配比特和功率,显著增加信道比特传输速率,改善系统整体性能.
