Abstract: A system for transmitting a wireless countermeasure signal to disrupt third party communications is disclosed that include an antenna configured to receive wireless signals and transmit wireless counter measure signals such that the wireless countermeasure signals are responsive to the received wireless signals. A receiver processes the received wireless signals to create processed received signal data while a spectrum control module subtracts known source signal data from the processed received signal data to generate unknown source signal data. The unknown source signal data is based on unknown wireless signals, such as enemy signals. A transmitter is configured to process the unknown source signal data to create countermeasure signals and transmit a wireless countermeasure signal over the first antenna or a second antenna to thereby interfere with the unknown wireless signals.

Abstract: A UE may store received samples of a wireless signal at cx1 to reduce memory usage, but then may correlate those samples with cx2 timing hypotheses to improve performance. The received sequence is resampled at cx2 instead of cx1. The UE still performs the correlation of the cx2 timing hypotheses for the performance gain, but the reference waveform is resampled with cx2 time offset. A Fast Fourier Transform (FFT) may be taken of the received and reference waveforms. In the frequency domain, resampling may be performed by multiplying the FFT of the reference waveform by a phase ramp—a pointwise multiplication in the frequency domain with a constant magnitude sequence whose phase varies linearly.
Abstract translation: UE可以以cx1存储无线信号的接收样本以减少存储器使用，但是然后可以将这些采样与cx2定时假设相关联以提高性能。 接收的序列在cx2而不是cx1重采样。 UE仍然执行cx2定时假设与性能增益的相关性，但参考波形用cx2时间偏移重采样。 可以对接收和参考波形进行快速傅里叶变换（FFT）。 在频域中，重采样可以通过将参考波形的FFT乘以频域中的相位斜坡 - 点相乘乘以其相位线性变化的恒定幅度序列来执行。
