This article studies the FFH in Chinese stock market under the Contract Theory.
结合配股权契约对我国证券市场＂功能锁定＂现象进行了研究。
Then, the performance of BCH coded FFH OCDMA system was analyzed, and was compared with uncoded FFH OCDMA system.
论述了BCH信道编码对FFH-OCDMA系统性能的影响，并将它和未编码的FFH- OCDMA系统进行了比较。
Analysis result shows that this scheme can improve the BER performance, and thus enhance the system capacity of FFH OCDMA.
结果表明。该方案能有效地改善FFHOCDMA系统误码率的性能，可增加系统的容量。
Meanwhile, synchronization is also the difficulty of the development of FH system, which needs supplicated design especially in the fast frequency hopping (FFH).
同时跳频同步也是跳频通信系统开发的难点，特别在高跳速工作时实现同步捕获和跟踪需要精心设计方案。
The results of simulation show that dispersion seriously reduces the peak power and sample energy on the FFH OCDMA system. Hence, bit error rate(BER) of system is increased by dispersion.
结果表明，在FFH-OCDMA系统中，光纤色散导致解码自相关光脉冲峰值功率和光脉冲取样能量的降低，进而导致系统误码率（BER ）的增加。
The highest bit is 1 the other 128 characters (80h-ffh) is called "extended ASCII", usually used to store the English tabs, part of the phonetic characters, and so some of the other symbols.
而最高位为1的另128个字符(80h—ffh)被称为“扩展ascii”，一般用来存放英文的制表符、部分音标字符等等的一些其它符号。
