High speed data packet access minimum mean squared equalization with direct matrix inversion training
Abstract:
The present invention provides a equalizer processing module operable to cancel interference associated with received radio frequency (RF) burst(s). This equalizer processing module includes a first equalizer processing branch and an optional second equalizer processing branch. The first equalizer processing branch is operable to be trained by applying a recursive DMI process such as a Levison algorithm, based upon known training sequences and equalize the received RF burst. This results in soft samples or decisions which in turn may be converted to data bits. The soft samples are processed with a de-interleaver and channel decoder, where the combination is operable to produce a decoded frame of data bits from the soft samples. This allows interfering signals to be cancelled and more accurate processing of the received RF bursts to occur.
