Abstract: A method and apparatus controls diversity reception in a wireless communication device. By determining a value based on a number of active set pilot signals received from a set of base stations, the wireless communication device dynamically enables or disables diversity reception. Diversity reception can be controlled by adjusting a diversity threshold based on the determined value. A channel quality indicator of a channel is measured and compared against the adjusted diversity threshold. The diversity reception mode is then enabled or disabled based on the comparison. For example, if the number of active pilot signals is above a predetermined value, indicating “good” coverage, the diversity threshold is decreased. The measured channel quality indicator is compared against the adjusted threshold, and diversity reception is enabled when the channel quality indicator is less than the decreased diversity threshold.

Abstract: Communication processing paths include distortions, such as DC offset in the baseband analog path which needs to be accounted for. The use of a digital-to-analog converter (DAC) to inject a DC offset cancellation signal can bring about noise/area/power advantages. The DAC is driven by a mixed signal low pass filter loop. However, the DAC could also be driven in an open loop system, or a combination of open and closed loop. A low noise sign and magnitude DAC with low area and power requirements is implemented using selectively connected programmable current sources to virtual earth input terminals on a transimpedance amplifier (TIA) op-amp circuit. The constant virtual earth voltage eliminates linearity problems that would otherwise exist due to the finite current source output impedance. Current sources are only switched in when required so unneeded sources are out of circuit and do not contribute noise or use any power.
