Selecting from among plural channel estimation techniques

摘要

A wireless receiver receives reference signals over a wireless link. The wireless receiver calculates a selection indication based on the received reference signals, and the wireless receiver selects from among plural channel estimation techniques based on the selection indication, where the selected channel estimation technique is usable to perform channel estimation of the wireless link.

主权项

1. A method comprising:
receiving, by a wireless receiver, reference signals over a wireless link; calculating, by the wireless receiver, a selection indication based on a quantity reflecting a difference between the received reference signals, the quantity being based on an aggregation of channel frequency responses and corresponding noise samples at plural frequencies; and selecting, by the wireless receiver, from among plural channel estimation techniques based on the selection indication; performing, by the wireless receiver, channel estimation of the wireless link using the selected channel estimation technique; and applying frequency domain noise suppression prior to performing the channel estimation using the selected channel estimation technique.
