complex orthogonal matrix
complex orthogonal matrix 双语例句
Though the coding ratio is less than 1, it is even more easy to construct from the traditional space-time coding; Grouping the subcarriers in the Orthogonal frequency division multiplexing through the block matrix method, and generalized complex orthogonal designed on each block subcarriers, space-frequency-Doppler coded OFDM for the general MIMO system is constructed, in which the coherent decoding error only lies on the channel frequency impulse response differences between the consecutive adjacent subcarriers in each block subchannels and thus significantly alleviates the influences of the time-varying Doppler fading on the coding transmission. Furthermore, without increasing any transmit redundancy, it achieves the system full diversity gains with high bandwidth efficiency.
其中第一种编码方式利用现有的线性空时码直接进行全分集级联空频循环编码，可有效对抗信道Doppler衰落，虽编码效率低于1，但实现起来相当简单；第二种编码方式利用矩阵分块方法对正交频分复用子载频分块，并按块进行空频复正交编码设计，实现了一般性MIMO系统中的空频多普勒OFDM编码，其相干解码误差只取决于子信道或信道块内相邻子载频间频率响应误差的大小，大大减少了时变Doppler衰落的影响，且在不增加系统传输冗余度的前提下有效地实现了系统全分集增益，有更高的频带利用率。
This paper proves that the real and imaginary parts of the complex eigenvector of a reflection matrix given in the object space or in the image space coordinate system are orthogonal to each other and they are both orthogonal to the real eigenvector of the same reflection matrix.

complex: 复杂的；
complementary: 补充的；
comprehensive: 综合的；
compensating: 补偿的
这组词都有“复杂的”的意思，其区别是：
complex: 侧重内在关系的复杂，需通过仔细研究与了解才能掌握和运用。
complicated: 与complex的含义接近，但语气更强，着重极其复杂，很难分析、分辨或解释。
sophisticated: 侧重指事物发展到或达到高级的程度所体现出的复杂。
intricate: 着重指错综复杂，令人迷惑理解。
