- Answer The formulas for calculating the magnitude and the phase from the real (Re) and imaginary (Im) numbers are: magnitude [dB] = 20 * Log(sqr(Re^2 + Im^2))

Aug 30, 2018 · To convert the file, you would need another GNU Radio flowgraph which consists of: Wav File Source block, to open your wav IQ file. Float to Complex block, to convert the stereo wav stream into the complex stream. Throttle block, to limit the rate of your CPU processing. File Sink, to write the complex stream into a .raw file.
- In-phase quadrature (I/Q) upconverters integrate an I/Q mixer, RF amplifier, 90° hybrid, and an LO buffer in one package. These devices are used in transmitter applications to upconvert intermediate frequency (IF) to a desired radio frequency (RF) while reducing the need for filtering unwanted sideband.
- The Inport block inside the RF Transmitter converts the complex baseband waveform into an RF signal. You can vary the center frequency of this RF signal by modifying the Intermediate frequency (MHz): parameter of the RF Transmitter block mask (in this example, the default frequency is 70 MHz). The Outport block converts the RF signal back into ...

Socket accept python timeoutCreate IQ waveform. We will create an IQ waveform that consists of two sinusoid signals with real and imaginary values. When generating signals for the RF Signal Generator ensure that the waveform is a continuous row vector.

Aug 20, 2018 · Because I captured the full RF Baseband (1,024 MHz sample rate), I will not use RTL SDR (osmocom Source Block) in GNU Radio, but using WAV file source, instead. The concept is very simple: Use WAV File Source Block to spits out baseband IQ file into GNU Radio, with stereo output. Convert the stereo IQ stream into a complex stream.

The receiver section contains all blocks necessary to receive RF signals and convert them to digital data that is usable by a BBP. There are two independently controlled channels that can receive signals from different sources, allowing the device to be used in multiple input, multiple output (MIMO) systems while sharing a common frequency synthesizer. Peter Gamma alias Yoyo2014 "Lab streaming layer is a system for synchronizing streaming data for live analysis or recording.
