Abstract
A method of estimating a wireless channel including determining a value of β from a finite set of discrete values for channel estimation in a slot N based on time-selectivity of a channel corresponding to the slot N; estimating the channel according to reference signal symbols received in the slot N; determining a transmit power level in a slot N−1, a transmit power level in the slot N, and a power offset ratio; identifying filtered channel coefficients in the slot N−1; and computing in real time filtered channel coefficients in the slot N according to a determined set of values β applied to generate a subset of equalized QAM symbols in the slot N, the estimated channel according to reference signal symbols received in the slot N, the determined power offset ratio, and the filtered channel coefficients in the slot N−1.
