Which of the following indicates the number of input bits that the current output is dependent upon?

Equalization, diversity, and channel coding are three techniques that can be used to improve the quality of a communication link's signal and overall quality of service. These techniques can be used independently or in combination.  Equalizers require periodic retraining in order to maintain effective ISI cancellation. Equalizers track the changing channel and adjust their filter characteristics over time.

Equalization, diversity, and channel coding are three techniques that can be used to improve the quality of a communication link's signal and overall quality of service. These techniques can be used independently or in combination. 
Equalizers require periodic retraining in order to maintain effective ISI cancellation. Equalizers track the changing channel and adjust their filter characteristics over time.

Here's some more information about each technique:
Equalization: A filtering technique that reduces the effects of frequency selective fading. Equalization compensates for intersymbol interference (ISI) created by multipath within time dispersive channels.
Diversity: A technique that mitigates flat fading. Diversity is mainly used in radio communication and is a common technique for combatting fading and co-channel interference and avoiding error bursts.
Channel coding: A technique that improves the reliability of communication by adding some form of redundancy to the transmitted signal.
