Abstract: Apparatus and method for reallocation of spectral resources in multiwaveform systems. One embodiment provides a base station operating in a narrowband spectrum and broadband spectrum that share a band allocation of RF spectrum. The base station includes a narrowband transceiver, a broadband transceiver, and an electronic processor coupled to the narrowband transceiver and the broadband transceiver. The electronic processor is configured to determine that a traffic load on the narrowband transceiver is increasing and determine a number of additional carrier channels based on the traffic load to operate the narrowband transceiver within a predefined blocking rate. The electronic processor is also configured to reduce a bandwidth of the broadband transceiver based on the number of additional carrier channels and assign additional carrier channels to the narrowband transceiver to operate the narrowband transceiver with the number of additional carrier channels.

Abstract: A system for low earth orbit (LEO) satellite communication. In one example, the system includes a control computer and a workgroup including a plurality of communication devices. Each communication device includes an electronic processor configured to establish a wireless network connection with the control computer, determine connectivity data associated with a signal between the communication device and a first LEO satellite, and transmit the connectivity data to the control computer via the wireless network connection. The control computer is configured to receive the connectivity data from each communication device, and select a first one of the plurality of communication devices as a primary communication device based on each of the connectivity data. The primary communication device is configured to receive media from a different one of the plurality of communication devices via the wireless network connection and transmit the media to the first LEO satellite.

Abstract: Base station device with reduced power consumption and method thereof. The base station device includes a transmitter configured to implement time-division multiple access (TDMA). The transmitter transmits payload signals in a TDMA frame including a first timeslot and a second timeslot, with one of the first timeslot and the second timeslot designated as an active timeslot and the other of the first timeslot and the second timeslot designated as an idle timeslot. The base station device includes an electronic processor coupled to the transmitter and configured to control transmission of calls through the transmitter. The electronic processor is configured to transmit payload signals during the active timeslot and de-key the transmitter during the idle timeslot. During a voice call, the electronic processor is configured to re-kay the transmitter during a portion of the idle timeslot to transmit synchronization information.

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: 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.
