Abstract
Methods and systems for processing an RF signal are disclosed herein. Aspects of the method may comprise utilizing a single input CORDIC and a single output CORDIC for synchronizing and demodulating a received signal, wherein the received signal may comprise one or more bit rates. The received signal may comprise a one megabit per second (Mbps) signal. The single input CORDIC may be configured to operate in a rotating mode and the single output CORDIC may be configured to operate in a rotating mode and/or an arctangent (ARCTAN) mode. A rotated output of the single input CORDIC may be correlated with a phase shift keying (PSK) synchronization (sync) word and a portion of the correlated rotated output of the single input CORDIC may be buffered.
