Reducing distortion in repeaters for OFDM signals

摘要

Certain aspects and features are directed to determining characteristics such as phase margin and gain margin of signals such as standardized orthogonal frequency-division multiplexing (“OFDM”) signals. In one aspect, a processing system can identify multiple carriers in an OFDM signal communicated by a repeater. The carriers include carriers from frequency guard band other than those used for communicating payload data or pilot data. The processing system can generate dynamic characteristic data to be sent via the carriers. The processing system can generate modulate the carriers with the dynamic characteristic data. The modulated power level of the carriers is less than a maximum level of noise filtered by a device receiving the OFDM signal.

1. A method for standardized orthogonal frequency-division multiplexing signals with standardized frequency guard length, the method comprising:
identifying a plurality of carriers in an orthogonal frequency-division multiplexing signal communicated by a repeater, the plurality of carriers comprising carriers other than carriers used for communicating payload data or pilot data; generating dynamic characteristic data to be communicated via the plurality of carriers; and modulating the plurality of carriers with the dynamic characteristic data, wherein a power level of the plurality of carriers as modulated is less than a maximum level of noise filtered by a device receiving the orthogonal frequency-division multiplexing signal.
