Patent ID: 8737499

Claim:
A method for wireless communication comprising: receiving a precoded orthogonal frequency division multiplexed (OFDM) signal; transforming the precoded OFDM signal to a frequency-domain to generate a received frequency-domain OFDM signal; performing, by a first channel estimator, a first frequency-domain channel estimation on the received frequency-domain OFDM signal to generate a first-frequency domain channel estimate; transforming the first frequency-domain channel estimate to a first time-domain channel estimate; performing a cancellation of co-channel interference by a multipoint equalization block in a time-domain using the first time-domain channel estimate and the received precoded OFDM signal; performing, to a first output of the multipoint equalization block, a cancellation of residual inter-symbol interference by a first cyclic coordinate ascend section in the time domain after performing the cancellation of co-channel interference; transforming, to the frequency-domain, a time-domain output of the first cyclic coordinate ascend section; performing a cancellation of inter-carrier interference on the received precoded OFDM signal by a second cyclic coordinate ascend section using the frequency-domain transformed output of the first coordinate ascend section after performing the cancellation of residual inter-symbol interference; transforming a second output of the multipoint equalization block from the time-domain to the frequency-domain to generate a frequency-domain equalized output; performing, by a second channel estimator, a second frequency-domain channel estimation on the frequency-domain equalized output to generate a second frequency-domain channel estimate; transforming the second frequency-domain channel estimate to a second time-domain channel estimate; and performing cancellation of residual inter-symbol interference by the first cyclic coordinate ascend section in the time-domain to the second time-domain channel estimate.
