Abstract

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.

Description

technical field [0001] The present application relates generally to wireless communication systems, and more particularly, to apparatus, systems, and methods for equalizing received wireless communication signals. Background technique [0002] Some wireless communication systems ("non-OFDM systems") may implement communication schemes other than Orthogonal Frequency Division Multiplexing (OFDM), eg, single-carrier communication schemes. [0003] Receivers operating in non-OFDM systems can utilize, for example, a time-domain decision feedback equalizer (DFE) to suppress inter-symbol interference. However, in systems utilizing long impulse response channels, eg in digital television (DTV) systems, the DFE may eg be relatively complex. Contents of the invention [0004] The application provides a device, comprising: [0005] a pre-decoding equalizer for determining a plurality of filter weights by applying blind equalization and least mean square (LMS) equalization to a wir...
