Abstract
Apparatus and methods construct parameters for a unit associated with a precoder to a channel. Embodiments include forming a plurality of values for precoder constructions, where the values may be obtained from applying a transmission quality criterion to each precoder construction for varying channels lengths. Each precoder construction may be built for a predetermined channel length with a different channel length for each precoder construction. A subset of the precoder constructions operate substantially over the entire distance range covered by the varying channels lengths.
Claims29
A method comprising:
- forming a plurality of values for a plurality of precoder constructions, each precoder construction built for a predetermined channel length, a different channel length for each precoder construction, the values obtained from applying a transmission quality criterion to each precoder construction for varying channel lengths.
A computer-readable medium that stores instructions, which when performed by a machine, cause the machine to:
- form a plurality of values for a plurality of precoder constructions, each precoder constructed to a predetermined channel length, a different channel length for each precoder construction, the values obtained from application of a transmission quality criterion to each precoder construction for varying channels lengths.
An apparatus comprising:
- a unit associated with a precoder, the unit including a filter such that, at an output of a feed forward filter of the precoder, a mean square error increase, due to a coupling with a channel having a length different from a length to which the precoder is constructed, is within a selected value.
A system comprising:
- a unit associated with a precoder, the unit including a filter such that at an output of a feed forward filter, a mean square error increase, due to a coupling with a channel having a length different from a length to which the precoder is constructed, is within a selected value;
- a processor communicatively coupled to the precoder-associated unit;
- a parallel bus;
- and
- a memory coupled to the processor through the parallel bus.
