Abstract

Techniques are disclosed to provide a data dependent delay for a multi-phase transmitter architectures. These techniques include identifying a current segment occupied by a symbol associated with in-phase (I) and quadrature phase (Q) data within a data constellation based upon the number of phases used. Once the segment is identified, vector components are calculated as a function of the segment used to re-map the symbol within the constellation defined in accordance with the number of phases. The data delay may be performed in the baseband or at the RF rate to time-align local oscillator clocks with the delayed data, which is represented as the calculated vector components, for transmission. Further modifications to the RF-DAC operation to facilitate operation with the multi-phase system are also disclosed.
