Abstract
Disclosed are embodiments of apparatuses and methods of use thereof for frequency domain (FD) chip level (CL) equalizers used in wireless receivers. The FD-CL-EQ may further selectively apply a higher order matrix inverse or a lower order matrix inverse in the calculation of a channel estimate based on whether interference is present or not. Further disclosed are embodiments of methods and apparatuses for estimating pilot signal-to-interference ratio (SIR) in the wireless receivers. Further disclosed are methods and apparatuses for compensating for phase errors in received demodulated data symbols to improve performance of the wireless receivers.
