摘要： An analog-to-digital converter (ADC) comprises a sample/hold (S/H) unit, a digital-to-analog converter (DAC), a comparing unit, and a control unit. The S/H unit samples a first analog signal. The control unit comprises a compensating unit. The compensating unit receives an indication signal, and compensates a current bit and all its less significant bits, such that the sum of the current bit and all its less significant bits approximates a bit weight of the current bit, when the indication signal indicates that the comparison result cannot be determined. The compensating unit then outputs the compensated current bit and all its less significant bits together with more significant bits of the current bit.

摘要： A method and system to reduce the noise floor of a communications system is disclosed. The system may be incorporated into any device that provides binary samples from a datastream, such as a cordless telephone system. The system is configured to determine a number of bits of the binary samples that are affected by noise. The system is then able to remove the noise by setting those bits to a fixed value. The fixed value may depend on whether the sample is positive or negative. The value to set may be chosen so that the least significant bits of each sample come as close as possible to 0 for that particular numerical representation system. The system can be integrated with other known signal processing methods.

摘要： An apparatus to enable half-duplexing capabilities in a two-way communication device is disclosed. The apparatus estimates the signal power and background noise of a first input signal and a second input signal during approximately the same period.

These determinations may include whether the estimated signal power of at least one of the first and second input signals exceeds a threshold value; whether the estimated signal power of the first input signal exceeds the sum of a first threshold value and the estimated background noise of the first input signal; and whether the estimated signal power of the second input signal exceeds the sum of a second threshold value and the estimated background noise of the second input signal. Other embodiments for use with two-way communication devices and related methods are also disclosed.
