Abstract
In some aspects, there is provided a method. The method may include estimating, based on a first signal-phase in a plurality of signal-phases associated with an input signal, a first channel impulse response; estimating, based on a second signal-phase in the plurality of signal-phases, a second channel impulse response; selecting, based on at least one characteristic of the estimated first channel impulse response and the estimated second channel impulse response, a signal-phase from the plurality of signal-phases; equalizing, based on the selected signal phase, the input signal to produce an equalized signal; and outputting, to a symbol detector, the equalized signal. Related systems, methods, and articles of manufacture are also disclosed.
Claims20
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
- estimate, based on a first signal phase in a plurality of signal phases associated with an input signal, a first channel impulse response;
- estimate, based on a second signal phase in the plurality of signal phases, a second channel impulse response;
- select, based on at least one characteristic of the estimated first channel impulse response and the estimated second channel impulse response, a signal phase from the plurality of signal phases;
- equalize, based on the selected signal phase, the input signal to produce an equalized signal;
- and
- output, to a symbol detector, the equalized signal.
A method of equalizing an input signal comprising:
- estimating, by a communication device based on a first signal phase in a plurality of signal phases associated with the input signal, a first channel impulse response;
- estimating, based on a second signal phase in the plurality of signal phases, a second channel impulse response;
- selecting, based on at least one characteristic of the estimated first channel impulse response and the estimated second channel impulse response, a signal phase from the plurality of signal phases;
- equalizing, based on the selected signal phase, the input signal to produce an equalized signal;
- and
- outputting, to a symbol detector, the equalized signal.
