基于FFT变换的酉空时码设计

The Design of Unitary Space-time Code Based on FFT

酉空时码(USTC)是一种可以在发送端和接收端都不需要知道信道状态信息时使数据能够可靠传输的一种空时编码方案,是一种适合未来3G/4G快衰落信道的空时编码技术.本文提出基于傅立叶变换的酉空时码设计方案并对其性能仿真分析.

Unitary space-time code is well-tailored for flat-fading channels where neither the transmitter nor the receiver knows the fading coefficients; it is suitable for the future 3G/4G mobile communication. A constellation of unitary space-time signals of The Fourier-based design method are mainly discussed and the performance are concluded through simulation.
