摘要： Systems and methods for adjusting radar transmission parameters based on congestion level measurements are disclosed. In some aspects, a congestion level of radar signals at a location in a vicinity of a radar source may be measured or otherwise determined. In some aspects, a transmission parameter of radar signals configured for transmission to the location by the radar source may be adjusted based on the congestion levels.

摘要： Systems and methods for predictive coordination of ego radar and interferer radar parameters are dsiclsoed. In some aspects, a processor associated with a first radar system transmitting a first radar waveform to detect a target may identify a presence of a second radar system transmitting a second radar waveform in a vicinity of the first radar system. The processor may further predict an upcoming interference by the second radar waveform of the detection of the target by the first radar system. In addition, the processor may, in response to the predicting the upcoming interference, determine an adjustment to a first parameter of the first radar waveform and/or to a second parameter of the second radar waveform.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may encode real samples of data to obtain encoded data based at least in part on adding one or more time domain complex samples to the real samples of the data, wherein a function of the one or more time domain complex samples is a known value, and wherein the function is a sum of exponentials of the one or more time domain complex samples. The first wireless communication device may transmit, to a second wireless communication device, the encoded data. Numerous other aspects are described.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for radar target tracking based on return signal strength. A wireless device, such as a radar device, may measure a received signal strength of a detected signal. The received signal strength may be associated with at least one bin of a radar image. The wireless device may compare the received signal strength to a filtered signal strength. The filtered signal strength may be associated with a threshold difference in signal strength from the filtered signal strength. The wireless device may track the at least one bin of the radar image in response to the received signal strength being less than or equal to the threshold difference in signal strength from the filtered signal strength.
