What is IQ sample rate?
There will always be a “sample rate”, the rate at which sampling is performed. Someone might say, “I have an SDR running at 2 MHz sample rate.” What they mean is that the SDR receives two million IQ samples per second. If someone gives you a bunch of IQ samples, it will look like a 1D array/vector of complex numbers.
What is IQ rate in communication?
IQ rate is the sampling rate of the baseband I/Q data in samples per second (S/s). Carrier frequency is the carrier frequency of the RF signal in Hz. Gain is the Tx gain applied to the RF signal in dB. Active antenna is the antenna port to use for this channel.
What is IQ modulation?
What's an IQ Modulator? An IQ modulator is a device that converts baseband information into RF signals. Internally, two double-balanced mixers are combined as shown below. By modulating with both in-phase (I) and quadrature (Q) inputs, any arbitrary output amplitude and phase can be selected.
What is IQ vector?
It is representation of the signal in the complex form i.e. real and imaginary. I refers to real part and Q refers to imaginary part. The binary data after data mapping(modulation bpsk,qpsk,qam) becomes complex and refers as IQ vector signal.
