本文提出了一种多符号封装正交频分复用（MSE-OFDM）技术。仿真结果表明，该方法特别适用于长冲激响应信道。MSE-OFDM与空间分集技术相结合，即使在低信噪比（SNR）的环境中，也能显著提高带宽效率。
In this paper, multiple-symbol encapsulated orthogonal frequency division multiplexing (MSE-OFDM) is proposed to be employed in a multipath fading channel. Simulation results demonstrate that this method is particularly suitable for channels with long impulse response. MSE-OFDM combined with the spatial diversity technique yields a significant improvement in bandwidth efficiency even in a low signal-to-noise ratio (SNR) environment.
