Abstract
A radio includes a radio frequency (RF) subsystem to process analog information. A digital subsystem receives input from the RF subsystem, and may include a frequency error estimator and a transmitter. The frequency error estimator may be configured to receive samples from the digital subsystem and to estimate a frequency misalignment, between transmitter and receiver, of each of a plurality of received signals in real time. The transmitter may be configured to transmit to each of a plurality of downstream endpoints on frequencies based in part on the respective estimated frequency misalignments. Such transmissions, at a frequencies expected by each of the downstream endpoints, allows the use of narrower receiver filters by those endpoints. In one example, the plurality of received signals may be received simultaneously and be associated with packets of a plurality of different channel plans, with different channel bandwidths and/or channel spacing, and different channel modulation schemes.
