Flexible adaptive equalizer
Flexible adaptive equalizer. Communications may be supported between two or more respective devices within a communications system via one or more available channels. Such channels may be different respective communication channels or may be logical partitions of a given communication channel. Appropriate adaptation and provision of resources within one or more devices within the system may be performed based upon any of a number of characteristics and/or considerations associated with one or more devices, channels, etc. within the system. A number of equalizer elements may be employed to perform processing of respective signal(s) received via respective channel(s). Adaptation of which equalizer elements are employed for the respective channels may be modified, adapted, etc. over time based upon any of such number of characteristics and/or considerations. Also, a number of pre-equalizer elements may also be employed to perform processing of signal(s) to be transmitted via respective channel(s).
