Abstract: A method of optimizing at least one IQMC parameter value for an IQMC includes: generating a set of tested IQMC candidate parameter values by performing an iterative method including selecting a first IQMC candidate parameter value for the at least one parameter of the IQMC; determining, using the first IQMC candidate parameter value, a performance metric value that comprises at least one of (i) an image rejection ratio (IRR) value, (ii) a signal-to-interference-plus-noise ratio (SINR) value, or (iii) a signal-to-image ratio (SImR) value; and determining a second IQMC candidate parameter value that is an update to the first IQMC candidate parameter value. The method of optimizing at least one IQMC parameter value for an IQMC further includes determining an IQMC candidate parameter value of the set of tested IQMC candidate parameter values that optimizes the performance metric.

Abstract: An apparatus is provided. The apparatus includes a processor configured to receive a synchronization signal (SS) and identify timing of the SS based on a primary spreading signal (PSS) in the SS, identify tentative secondary spreading signals (SSSs) based on the identified timing, and group the tentative SSSs; a register configured to receive the SS; and a memory configured to store the tentative SSSs for each group of the tentative SSSs; wherein the processor is further configured to cross correlate the tentative SSSs, combine cross correlated outputs with weights by group, determine an SSS as the tentative SSS with a maximum combined cross correlation outputs, and determine a cell identification based on the determined SSS.

Abstract: A method of pre-compensating for transmitter in-phase (I) and quadrature (Q) mismatch (IQMM) may include sending a signal through an up-converter of a transmit path to provide an up-converted signal, determining the up-converted signal, determining one or more IQMM parameters for the transmit path based on the determined up-converted signal, and determining one or more pre-compensation parameters for the transmit path based on the one or more IQMM parameters for the transmit path. In some embodiments, the up-converted signal may be determined through a receive feedback path. In some embodiments, the up-converted signal may be determined through an envelope detector.
