摘要: Certain aspects and embodiments are directed to a Doppler shift correction sub-system that can be disposed in a mobile repeater. The Doppler shift correction sub-system can include a processor and a frequency-shifting module. The processor can be configured to determine a corrective frequency shift based on a velocity of the repeater relative to a source and a representative transmission frequency. The processor can provide the corrective frequency shift to a frequency-shifting module. The frequency-shifting module can be configured to shift the signal using the corrective frequency shift prior to transmitting the signal to a destination, such as a mobile device.

摘要: A radar hardware accelerator (HWA) includes a fast Fourier transform (FFT) engine including a pre-processing block for providing interference mitigation and/or multiplying a radar data sample stream received from ADC buffers within a split accelerator local memory that also includes output buffers by a pre-programmed complex scalar or a specified sample from an internal look-up table (LUT) to generate pre-processed samples. A windowing plus FFT block (windowed FFT block) is for multiply the pre-processed samples by a window vector and then processing by an FFT block for performing a FFT to generate Fourier transformed samples. A post-processing block is for computing a magnitude of the Fourier transformed samples and performing a data compression operation for generating post-processed radar data. The pre-processing block, windowed FFT block and post-processing block are connected in one streaming series data path.

摘要: Systems and methods are disclosed for extending the communication range of mobile communication devices. A long-range radio device is controlled by a control application on a host smartphone. The long-range radio device provides signal paths for two different radios, one employing a long-range (LoRa) modulation format, and another employing a high data-rate encoding such as FSK. The system provides graceful degradation in data rate as radio link distance increases and received signal strength decreases. In addition to switching between radios, variable compression and buffering are used to adapt usage to supportable data rates. Voice, other audio, video, text, binary, and other data formats are supported, as also a wide range of co-resident host apps. Unidirectional and bidirectional links can be used.

摘要: Provided is a transmission apparatus capable of reducing power consumption of a reception apparatus. The transmission apparatus includes a modulator that modulates a data signal to generate a transmission signal. The modulator modulates the data signal by assigning the data signal to a frequency difference between a first frequency and a second frequency in a carrier.

摘要: Embodiments of the present invention disclose systems and methods for providing an ATC Overlay data link. Through embodiments of the present invention, existing ATC (or other) modulated signals using existing standard frequencies may be utilized to transmit (e.g., from an aircraft transponder) additional information in a manner that does not render the transmitted signal unrecognizable by legacy ATC equipment. Legacy equipment will be able to demodulate and decode information that was encoded in the transmitted signal in accordance with preexisting standard modulation formats, and updated equipment can also extract the additional information that was overlaid on transmitted signals.

摘要: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention relates to method and apparatus for performing a decoding with low complexity in a wireless communication system. A decoding method of a terminal in a wireless communication system comprises determining a first characteristic value indicating a statistical characteristic of an interference signal based on a received signal of a base station, determining a second characteristic value indicating a statistical characteristic of an interference signal based on data received from the base station, and decoding the data according to a decoding scheme corresponding to a difference of the first characteristic value and the second characteristic value.
