At least integrated when using one channel, the CIR estimation and integrated filter weights at least one antenna, space optimal filter (JSTOF)

摘要

A wireless communications device may include at least one virtual antenna, and a space-time filter circuit for filtering a communications signal received by the at least one virtual antenna by jointly estimating space-time filter weights and at least one channel impulse response (CIR). The wireless communications device may further include a matched filter circuit downstream from the space-time filter circuit and having a filter response that is provided by a channel impulse response estimation from the space-time filter circuit.
