Adaptive low-complexity channel estimation

摘要

Systems, methods, and other embodiments associated with adaptive low-complexity channel estimation are illustrated. In one embodiment an integrated circuit includes a controller configured to control a switch to select between a plurality of processing paths that each perform channel estimation using a different order of operations to process an orthogonal frequency-division multiplexed (OFDM) signal.

1. A device comprising:
a controller configured to control a switch to select between at least two processing paths when performing channel estimation processing of an orthogonal frequency-division multiplexed (OFDM) signal, wherein the at least two processing paths include: a first processing path configured to process the OFDM signal according to a first order of processing operations; and a second processing path configured to process the OFDM signal according to a second order of processing operations, wherein the first order of processing operations is different from the second order of processing operations; wherein the controller is further configured to:
select the first processing path if a frequency correlation for the OFDM signal is within a predetermined frequency threshold; andselect the second processing path if i) a time correlation for the OFDM signal is within a predetermined time threshold, and ii) the frequency correlation is not within the predetermined frequency threshold.
