Abstract:
1. A method of generating information for use in detecting a signal, the method comprising: generating a plurality of respective correlation signals from i) a plurality of received signals and ii) a spreading sequence, wherein the plurality of received signals correspond to a plurality of respective antennas, each received signal includes an in-phase (I) signal and a quadrature (Q) signal, and each generated correlation signal includes an I correlation signal and a Q correlation signal; generating a plurality of respective magnitude signals from the plurality of correlation signals, each magnitude signal generated by adding i) the maximum of the magnitudes of a respective I correlation signal and a respective Q correlation signal with ii) a fraction of the minimum of the magnitudes of the respective I correlation signal and the respective Q correlation signal, wherein the respective I correlation signal and the respective Q correlation signal are outputs from a respective correlator; generating a respective plurality of time-delayed versions for each of the plurality of respective magnitude signals, wherein each of the time-delayed versions in the respective plurality of time-delayed versions is delayed by a respective integer number of symbol periods; generating a plurality of time-domain averaged signals for the plurality of respective magnitude signals, wherein each of the plurality of time-domain averaged signals is generated based on i) the respective magnitude signal and ii) the respective plurality of time-delayed versions for the respective magnitude signal; generating a first spatial-domain averaged signal based on the plurality of magnitude signals; generating a second spatial-domain averaged signal based on the plurality of time-domain averaged signals; and generating a multiple antenna peak-to-average signal based on i) the first spatial-domain averaged signal and ii) the second spatial-domain averaged signal.
