摘要： Improved radio receiver designs can be used in the operational environment of wireless telephone communications. The radio receiver includes a variable attenuator, an RF signal amplifier, and a controller. The controller controls the amount of attenuation provided by the variable attenuator in response to signals received by the RF signal amplifier. The controller adjusts the variable attenuator to achieve a minimum symbol error rate and/or to maximize the signal-to-noise and interference ratio for a desired signal, irrespective of the levels of any interfering signals received by the RF signal amplifier. In this manner, the variable attenuator is adjusted to obtain just the right amount of intermodulation performance for a given set of receiving conditions. This technique saves operating current and minimizes noise figure because, in practice, interference conditions do not persist all of the time, and are usually of temporary duration.

摘要： Systems and methodologies are described that facilitate multimode communication in wireless networks. Receiving and/or transmitting components can comprise a plurality of receive paths over which antennas can forward concurrently received signals to facilitate simultaneous or shared receiving of signals related to disparate communication technologies. The receive paths can be implemented by one or more multiplexers (e.g., diplexers, triplexers, etc.) to facilitate separating signals simultaneously received over disparate bands. In addition, antenna switching is described to facilitate shared receiving. Multimode transmitting is similarly provided. In particular, voice, data and global positioning system (GPS) signals can be concurrently received and processed by a wireless device.

摘要： Improved radio receiver designs are disclosed that can be used in the operational environment of wireless communications. The radio receiver includes a signal input terminal, a variable-current RF signal amplifier, a demodulator, and a controller. The variable-current RF signal amplifier has an input terminal for accepting RF input signals, an output terminal for generating an amplified version of the RF input signals, and a current control terminal for controlling the current consumption of the RF signal amplifier. The signal input terminal is coupled to the input terminal of the variable-current RF signal amplifier, the output terminal of the variable-current RF signal amplifier is coupled to the demodulator, and the current control terminal is coupled to the controller. The controller is also coupled to the demodulator. A received signal, including any noise and/or interference, is coupled to the signal input terminal. In response to signals amplified by the RF signal amplifier and demodulated by the demodulator, the controller controls the current consumed by the variable-current RF signal amplifier. The controller adjusts the current consumed by the RF signal amplifier to achieve at least a minimum acceptable signal-to-interference ratio for a desired signal, while the Noise Figure is not degraded any more than is necessary to achieve a minimum acceptable signal-to-interference ratio at any given time. In this manner, the variable current RF signal amplifier is adjusted to obtain a required amount of intermodulation performance for a given set of receiving conditions. This technique saves operating current and maintains fade margins because, in practice, interference conditions do not persist all of the time, and are usually of temporary duration.
