Frequency domain equalization for wireless communication

摘要

Some demonstrative embodiments include devices, systems and/or methods of equalizing received wireless communication signals. For example, a device may include a pre-decoding equalizer to determine a plurality of filter weights by applying both a blind-equalization and a least-mean-squares (LMS) equalization to a wireless communication signal received over a wireless communication channel; a channel estimator to estimate a channel frequency response of the channel based on the filtering weights; and a turbo-equalization scheme including a decoder to decode the wireless communication signal and a turbo equalizer to equalize the decoded wireless communication signal using the estimated channel frequency response.

1. An apparatus comprising:
a pre-decoding equalizer to determine a plurality of filter weights by applying both a blind-equalization and a least-mean-squares (LMS) equalization to a wireless communication signal received over a wireless communication channel; a channel estimator to estimate a channel frequency response of the channel based on the filtering weights, the channel frequency response including a plurality of channel coefficients corresponding to a respective plurality of channel subcarriers, the plurality of channel coefficients satisfying a criterion relating to a peak threshold and a width threshold; and a turbo-equalization scheme including a decoder to decode the wireless communication signal and a turbo equalizer to equalize the decoded wireless communication signal using the estimated channel frequency response.
