Abstract
In some embodiments, an receiver in wireless communication may determine whether channel smoothing should be used in channel and noise estimation. The receiver may obtain pre-smoothing channel estimation using one or more training symbols in a digital wireless frame, and obtain post-smoothing channel estimation by performing smoothing operation over the pre-smoothing channel estimation. The receiver may obtain pre-smoothing estimated noise using the one or more training symbols, and obtain post-smoothing estimated noise based on the post-smoothing channel estimation. The receiver may compare the pre-smoothing estimated noise and the post-smoothing estimated noise. If the post-smoothing estimated noise has a noise power no larger than the pre-smoothing estimated noise power or a weighted pre-smoothing estimated noise power, where the weight can be predefined or configured, post-smoothing channel and noise estimation may be used. Otherwise, pre-smoothing channel and noise estimation may be used. The receiver may be an orthogonal frequency-division multiplexing (OFDM) receiver.
