摘要

OSTBC代表正交空时块编码。它比空时编码具有更多的优点。OSTBC4已经使用了有限数量的接收天线，但在本文中，我们使用5个接收天线来寻找大型MIMO的性能。OSTBC可以支持2个以上的天线。OSTBC使用线性STBC。所有信号彼此正交。此外，正交性使我们能够根据不同的特性实现充分的传输;同时，它允许基本的ML解码。预编码的OSTBC具有较高的展开多面体质量和较低的编码和其他两种编码，因为在预编码的OSTBC中需要将数据图像一起规划和解码。OSTBC编码器片对来自PSK调制器的数据图像进行编码，利用用于两个发射接收设备的Alamouti码或用于三个或四个发射无线电线的其他综合复杂正交码。OSTBC通过三个信道进行误码率与信噪比的分析，并采用零强迫解码器。OSTBC在信噪比方面的性能优于STBC。

Performance of OSTBC5 through three different channels using zero forcing equalizer in MIMO system

OSTBC stands for orthogonal space time block coding. It gives more advantages then space time coding. OSTBC4 already use with limited number of receiving antenna but in this paper we use 5 receiving antennas to find the performance of the large MIMO. OSTBC perform function for more than 2 antennas. The OSTBC use linear STBC. All signals orthogonal to each other. The orthoganality empowers us to accomplish full transmit differing qualities according to furthermore; in the meantime, it permits a basic ML deciphering. Precoded OSTBC has a higher unraveling many-sided quality and a lower coding and other two codes, since in the precoded OSTBC the data images should be together planned and decoded. The OSTBC Encoder piece encodes the data images from the PSK Modulator by utilizing either the Alamouti code for two transmit reception apparatuses or other summed up complex orthogonal codes for three or four transmit radio wires. OSTBC perform the analysis between the BER vs SNR through three channels with zero forcing decoder. The OSTBC has best performance related to signal to noise ratio than STBC.
