Abstract
Aspects of the subject disclosure may include, for example, a waveguide system that includes a transmission device having a coupler positioned with respect to a transmission medium to facilitate transmission or reception of electromagnetic waves that transport communications data. The electromagnetic waves propagate along an outer surface of the transmission medium. A training controller detects an impairment on the transmission medium adverse to the transmission or reception of the electromagnetic waves and adjusts the electromagnetic waves to reduce the effects of the impairment on the transmission medium. Other embodiments are disclosed.
Claims21
A waveguide system, comprising:
- a coupler that is positioned with respect to a transmission medium to facilitate transmission of electromagnetic waves that propagate along an outer surface of the transmission medium, wherein the electromagnetic waves transport communications data;
- and
- a training controller that detects an impairment on at least a portion of the outer surface of the transmission medium that is adverse to the transmission of the electromagnetic waves and that adjusts the electromagnetic waves to reduce adverse effects of the impairment, wherein the training controller adjusts an envelope of the electromagnetic waves to place a local minimum of the envelope in a location that corresponds to at least one of:
- a position of the impairment on the at least the portion of the outer surface of the transmission medium or azimuthal orientation of the impairment on the outer surface of the transmission medium.
A method comprising:
- facilitating, via a transmission device, transmission or reception of electromagnetic waves that propagate along an outer surface of a transmission medium, wherein the electromagnetic waves transport communications data;
- detecting an impairment on the outer surface of the transmission medium that is adverse to the transmission of the electromagnetic waves;
- and
- adjusting an envelope of the electromagnetic waves to mitigate adverse effects of the impairment, wherein adjusting the envelope of the electromagnetic waves includes adjusting at least one carrier frequency of the electromagnetic waves based on feedback data received from at least one remote transmission device coupled to receive the electromagnetic waves.
A waveguide system, comprising:
- a transmission device including a coupler, wherein the coupler is positioned with respect to a transmission medium to facilitate transmission or reception of electromagnetic waves that propagate along an outer surface of the transmission medium;
- and
- a training controller, coupled to the transmission device, that detects an impairment on the transmission medium adverse to the transmission or reception of the electromagnetic waves and that adjusts the electromagnetic waves to place a local minimum in a location that corresponds to the impairment on the transmission medium.
