ABSTRACT:
A wireless transceiver including an oscillator, a radio, a baseband processor and MAC device that performs apiori frequency offset correction. The radio converts between RF signals and baseband signals. The baseband processor includes a frequency correction loop, an inverter and a combiner. The frequency correction loop generates a frequency offset signal based on a frequency difference between an oscillator reference frequency and frequency of a received signal. The inverter inverts the frequency offset signal and the combiner adjusts frequency of a transmit signal by the inverted frequency offset signal. The MAC processes received packets, identifies packets received from an AP, provides packets to the baseband processor for transmission, and controls the baseband processor to adjust transmit signals to a frequency of the AP. The baseband processor may include a memory or filter to store or update frequency offset values.
