Abstract
An equalization method has been developed for low latency, low bandwidth wireless communication channel environments. With this method, an exact copy, nearly exact copy, or some facsimile of a message (or associated information), which was transmitted via a low latency, low bandwidth wireless communication channel, is also sent via a backend communication channel such as a fiber optic network. Equalization is generally performed by comparing the originally received message to the copy sent via the backend channel. The original message can incorporate an added channel delay to compensate for the time delay between the primary wireless channel and the backend channel.
Claims23
A method, comprising:
- receiving a signal over a primary communication channel;
- receiving at least a representative copy of the signal over a backend communication channel;
- and
- equalizing the primary communication channel with a first equalizer by comparing the signal with the representative copy.
A method, comprising:
- receiving a signal over a primary communication channel;
- receiving at least a representative copy of the signal over a backend communication channel;
- and
- reducing a time domain for an equalizer by evaluating an effect of removing feed forward delay stages.
