    Abstract: Spectral efficiency is improved by assigning uplink channels according to expected receive signal levels at a serving base station. A first subscriber device detects a new call request indication, and then determines, as a function of its transmit power level and current location relative to the serving base station, an expected receive signal strength indication (RSSI) at its serving base station. Depending on whether it is determined that the expected RSSI is greater than or less than a RSSI threshold: one of (i) transmitting a call request to the serving base station requesting an assignment to a respective designated high-power or low-power channel for the new call and (ii) transmitting the new call on a respective pre-allocated high-power or low-power channel.

    Abstract: Apparatus and method for linearizing narrowband carriers with low resolution predistorters are provided. The method includes amplifying, using a power amplifier, one or more broadcast carriers and linearizing, using a predistorter coupled to the power amplifier, the one or more broadcast carriers. The method also includes determining, using an electronic processor, a composite bandwidth of the one or more broadcast carriers and determining, using the electronic processor, whether the composite bandwidth is below a modulation bandwidth of the predistorter. The method further includes controlling, using the electronic processor, a pacification carrier generator coupled to the electronic processor to combine a pacification carrier with the one or more broadcast carriers when the composite bandwidth is below the minimum modulation bandwidth of the predistorter.

    Abstract: A base station device and a method for multi-carrier crest factor reduction are provided. The method includes generating, using a plurality of radio frequency sources, a plurality of radio frequency carrier signals. The method also includes initiating modulation, using a plurality of carrier modulators, of a first subset of the plurality of radio frequency carrier signals with information signals at a first time to generate a plurality of modulated signals and initiating modulation, using the plurality of carrier modulators, of a second subset of the plurality of radio frequency carrier signals with the information signals at a second time to generate the plurality of modulated signals. The second time is a predetermined time offset after the first time. The method also includes transmitting, using one or more antennae, a multi-carrier signal including the plurality of modulated signals.

    Abstract: Methods and systems for improving adjacent channel rejection performance in a wireless signal by a radio device in a mobile network. In one embodiment, a mobile radio network includes a first radio device (e.g., a subscriber), a second radio device, and a fixed radio apparatus (e.g., a base station or repeater). The first radio device receives a first channel signal having a first frequency offset with respect to a reference frequency. The first channel signal is associated with the second radio device. The first radio device measures the first frequency offset, determines a second frequency offset for a second channel signal, and transmits the second channel signal with the second frequency offset.
