Patent ID: 8467439

Claim:
A method performed at a node of a wireless network to adaptively switch equalization operations, the method comprising: receiving wirelessly a signal from a transmitter; estimating a post-equalization signal-to-interference-plus-noise (SINR) performance γ T of a turbo equalization operation based on the received signal; and selecting, based on the estimated post-equalization SINR performance γ T of the turbo equalization operation, one of a turbo equalization operation and a linear equalization operation to equalize the received signal, wherein the step of estimating the post-equalization SINR performance γ T of the turbo equalization operation comprises: determining per-subcarrier SINRs for a plurality of subcarriers allocated to the received signal; determining per-subcarrier capacities for the subcarriers allocated to the received signal based on the per-subcarrier SINRs; and estimating a post-equalization SINR performance γ T of the turbo equalization operation based on the per-subcarrier capacities of the subcarriers.
