1. An apparatus, comprising:
a radio frequency (RF) receiver that receives packets, the RF receiver comprising first and second synchronization field detectors (SFDs) that detect synchronization headers generated using first and second physical layer (PHY) modes, respectively, wherein the first PHY mode is different than the second PHY mode, and wherein the first SFD receives an input signal of a Coordinate Rotation Digital Computer (Cordic) circuit, and wherein the second SFD receives an output signal of the Cordic circuit.
