And it turns out that the bit error rate of passband equalizer is smaller than that of baseband equalizer , but the convergent stability of baseband equalizer is better than that of passband equalizer . at the same time , baseband equalizer can be implemented in hardware more easily than passband equalizer 通帶均衡系統(tǒng)的誤碼率總是小于基帶均衡系統(tǒng)的誤碼率;但基帶均衡器收斂后的穩(wěn)定性要比通帶均衡器好,且基帶均衡器的采樣頻率較低,易于硬件實現(xiàn)。
