    摘要: 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.

    摘要: Certain aspects of determining a signal quality metric in event of a CRC false positive may comprise measuring an amplitude and/or phase of at least a portion of a phase shift keyed section of a frame. The measured amplitude and/or phase may be checked to determine if it lies within a range of a reference amplitude and/or phase respectively. An amplitude and/or phase counter may be incremented if the measured amplitude and/or phase lies outside the range of the reference amplitude and/or phase respectively. A confidence level value of a cyclic redundancy check (CRC) for at least a portion of the phase shift keyed section of the frame may be determined based on a determined value of the incremented amplitude and/or phase counter.
