attainable to meaning in English

adj.可达到的

The nonlinear filtering for nbi estimate - subtract assumes that the prediction error is dominated by spread spectrum signal and the background noise power is far below spread spectrum chip power , this assumption promises the low error ratio of chip decision but may not be attainable to digitalized dsss receiver in military communication environment , and does not coincide with the principle of dsss communication that decreases bit error ratio ( ber ) depending on spread spectrum gain , not on chip power
在干扰估计抵消滤波中,以往的非线性滤波要求干扰抵消滤波后扩频信号功率远大于残余噪声功率,进而假设码片判决的误码片率基本为零,这一要求对军用扩频通信是不利的,而且也不符合扩频通信利用扩频增益降低误码率的原则。
