A novel frequency time spreading code by designating the different frequencies to the different mark positions of the modified prime code is proposed.
通过对改进素数码的不同脉冲位置赋予不同的频率，提出了一种新的跳频扩时码。
Comparing with the conventional MC-CDMA system, the main difference is that this scheme performs the spreading in the time and frequency domain simultaneously.
与传统的MC - CD MA系统相比，其主要区别是该方案同时在时域和频域进行扩频。
