ABSTRACT:
Various aspects of a method and system from signal quality measurement based on mean phase error magnitude of a signal are presented. Aspects of the system may comprise circuitry that receives a time phase corrected Bluetooth signal via an RF channel. The circuitry may generate a phase error signal based on the received time phase corrected Bluetooth signal, and generate a mean phase error signal based on the generated phase error signal. A signal to noise ratio (SNR) may be derived based on the generated mean phase error signal, and a data rate may be selected based on the derived SNR.
