摘要： 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.

摘要： In RF transceivers, a method and system for using phase shift key (PSK) sync word for fine tuning frequency adjustment are provided. One aspect of the invention provides for adjusting a local oscillator frequency in a radio frequency (RF) receiver when a residual DC offset remains after a coarse frequency offset adjustment if performed. The fine adjustment may be necessary because of the synchronization required with a PSK-based modulated portion of a Bluetooth packet. A residual phase shift detected in a sync sequence portion of the Bluetooth packet may be utilized to determine a residual or fine frequency adjustment. This approach may allow an RF receiver to operate, in some instances, without the need for an equalizer. In this regard, the power consumed by the RF receiver may be minimized and/or the overall cost of the RF receiver may be reduced.

摘要： A method and system for an RDS decoder for single chip integrated Bluetooth and FM Transceiver and baseband processor are provided. The RDS decoder may have two phases, an acquisition phase and a decoding phase. During an acquisition phase, synchronization of a bit stream may be established based on detecting at least a portion of a plurality of received radio data service (RDS) data blocks. The synchronized bit stream may then be decoded during the decoding phase. If during decoding, at least a portion of the bit stream is out of synchronization, the bit stream may be synchronized without returning to the acquisition phase.

摘要： A method for temperature compensation of transmit power of a wireless communication device begins by measuring transmit power of the wireless communication device at a first temperature-based biasing condition to produce a first measured transmit power. The method continues by measuring transmit power of the wireless communication device at a second temperature-based biasing condition to produce a second measured transmit power. The method continues by determining ambient temperature of at least a portion of the wireless communication device based on the first and second measured transmit powers and a relationship between the first and second temperature-based biasing conditions. The method continues by compensating transmit power level of the wireless communication device based on the ambient temperature.
