This paper describes a method of suppressing correlation jamming at the frequency of reference signal which cannot be suppressed by lock-in amplifier and Boxcar integrator.

锁定放大器和取样积分器都不能抑制与参考信号同频率的干扰。 本文提出了一种能抑制这种干扰的方法。

If a review of the frequency distributions for each source points to a many-to-one condition and one source has only unique values, then it is a likely reference source.

如果查看每个源的频率分布发现存在多对一的情况，并且一个源只有一个惟一的值，那么它很可能就是引用源。

But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of power spectral density of the reference signal.

若上述正实条件仅在某些频带上满足，则FXLMS算法的收敛将依赖于参考信号功率谱密度的分布。

The markets that do the sort of high volume, low margin trades that would be affected by an FTT are the foreign exchange (FX), futures, options and stock markets (with special reference to high frequency trading of the often demonised computer algorithm type).

Then through the use of GPS-based reference clocks at each tower (for both time and frequency), the signals are synced so each can emit a perfect copy of both signal and symbol data.
