摘要： A method and apparatus are provided for use in a transceiver of a wireless system that enable analog mode operations to be performed using in-phase (I) and quadrature (Q) values. When operating in the analog mode, the apparatus comprises a processor that receives digital I, Q pairs relating to audio or data signals and performs FM demodulation to generate information content relating to the audio or data signals. When receiving data in the analog mode, the data is in a particular format.

摘要： A method and apparatus are provided for use in a transceiver of a wireless system that enable analog mode operations to be performed using in-phase (I) and quadrature (Q) values. The apparatus comprises a processor that performs FM modulation to generate I, Q pairs when operating in the analog mode. When transmitting in the analog mode, the processor encodes a digital representation of the signal to be transmitted into I, Q pairs and outputs the I, Q pairs to a digital-to-analog converter (DAC) comprised by the apparatus. The DAC converts the digital I, Q pairs into analog signals and outputs the analog signals to a cosine wave generator, which generates an in-phase cosine wave and an out-of-phase cosine wave having amplitudes that are proportional to the I and Q values, respectively. The cosine waves are summed for transmission over air. When receiving in the analog mode, a digital down converter converts the received signal into digital I and Q values. The processor then demodulates the I and Q values into a digital representation of the received signal to extract the signal content. When transitioning from transmitting data to transmitting audio, and vice versa, the processor ensures that abrupt changes in the phases of the I, Q pairs do not occur.

摘要： A method and system for optimally combining noisy measurements of attributes to obtain a composite statistically useful attribute result is disclosed. The method includes measuring a signal to noise ratio for each carrier in a pair, computing a signal to noise ratio power which is derived from said signal to noise ratio of each carrier in the pair and adding said signal to noise ratio powers that have been received within a predetermined period of time until the sum of said signal to noise ratio powers reaches a first threshold. The method continues with computing a weight based on the percentage of each measurements signal to noise ratio power in relation to said sum of said signal to noise ratio powers and deriving a statistically useful attribute result based at least in part on said weight of each signal to noise ratio power.

摘要： A method of adaptively determining a threshold for determining whether an error associated with a frame is an erasure or the result of a discontinuous transmission (DTX) uses a sample set of recently received frames yet avoids undesirable influences on the threshold that otherwise might be caused by the number of erasures in the sample set. A disclosed example uses a histogram-based approach and a simulated sort through the histogram to determine an appropriate threshold value. In a disclosed example the lesser of a bad frame threshold guideline value and a good frame threshold guideline value provide the threshold used to distinguish between a DTX and an erasure.
