  • Patent number: 10951247
    Abstract: Methods, systems, and devices for channelizing a wideband waveform for transmission on a spectral band comprising unavailable channel segments are described. Generally, the described techniques provide for transmitting and receiving wideband waveforms when channels of a system bandwidth are unavailable for transmission. A transmitter may separate a first wideband signal into segments, with each segment a bandwidth corresponding to a channel of the system bandwidth, and may map the segments to the available channels. The transmitter may combine the mapped segments into a second wideband waveform and transmit the second wideband waveform using the available channels. A receiver may receive a first wideband signal waveform and may separate the first wideband signal waveform into segments, de-map the segments and combine the de-mapped segments into a second wideband waveform for demodulation. The techniques may be used to transmit and receive wideband waveforms over tactical data links.

  • Patent number: 10931324
    Abstract: Techniques for a communication device with a receiver to dynamically control the gain of an analog front end of the receiver. Rather than having a single circuit path in the analog front end, the analog front end includes multiple circuit paths, and dynamically selects one of the circuit paths that optimizes the gain of the analog front end. For example, an amplifier circuit path may be selected to amplify the power level of the signal received from the antenna. However, the analog front end may further include an attenuator circuit path that includes an attenuator to reduce the power level of a high-power input signal received from the antenna to ensure that the high-power signal is attenuated below a power level associated with saturation of the receiver.
